For DC, a congestion charge is not the way to go
One problem with a congestion charge, federal government vehicles probably would be exempt, and foreign embassies and organizations like the World Bank probably wouldn't pay. Daily Mail photo, "Foreign embassies owe £75m in unpaid London congestion charges and U.S. diplomatic staff have racked up the most debt with fines totalling £8.1m."
WAMU-FM/NPR reports that DC City Council has allocated money to study the imposition of a congestion charge ("Should D.C. Toll Streets During Peak Traffic Periods? Council Wants To Study ‘Congestion Pricing’").
Congestion charges have two different purposes.
(1) reduce traffic by inducing people to shift trips to other modes or to not make trips altogether. (And by reducing traffic, they help to speed up the remaining traffic, including surface bus transit.)
This is done through the classic recommendations of instituting a "tax" where spillover costs are not normally captured within pricing.
(2) provide an additional source of funding for transportation projects, ideally prioritizing sustainable mobility initiatives.
First, much of the metropolitan area's "worst" congestion is in the suburbs, and is on highways, not in DC proper, although getting to and from DC is one of the contributing factors.

Most studies that rank "DC" bad for traffic call the entire metropolitan area after the center city. The fact is that DC does have a problem with congestion on certain streets in the core (K Street, I Street primarily) the reality is that most of the streets in the core aren't that congested.
Transit--Metrorail primarily despite its current problems--works!

Washington Capitals fans exiting the Metrorail system. One great thing about having the city's main arena in the core, served by 3 subway lines directly, and just a few blocks from 3 more lines, is how even a preponderance of suburbanites take transit to events held there.
I make this statement by the fact that during rush hour, it's possible to run red lights on a bicycle without any fear of oncoming traffic.
The major exception is the main commuter arteries such as 16th Street, Blair Road, Rhode Island Avenue, New York Avenue (itself congested because of the way it connects I-95 and I-695 for through trips to Virginia and Maryland). Although, some of this traffic would be interdicted I supposed by people switching to other modes in response to a congestion charge in Downtown.
Second, and most importantly, for DC to successfully levy a congestion charge, it has to be inalterably the #1 destination in the region for commerce subject to minimal competition for business relocation.
That's the case in cities like Singapore, Stockholm, or London, which have already instituted congestion charges, or New York City for Lower Manhattan, which has agreed to include a congestion charge going forward--not because they care that much about congestion, but because they need a funding source for rehabilitating the New York City Subway system.
I don't think it's the case for DC. Especially with the current federal administration and its willingness to eliminate agencies altogether or move them outside of DC and the DC metropolitan area.
My paralyzing fear is that Maryland and Virginia would actively market business relocation against DC, making the point that you can get to their business districts without having to pay a congestion charge.
I don't think either state or its jurisdictions can really be trusted on this.
In fact, when I saw a presentation by the then planning director of Arlington County at the National Building Museum in 2002, I went up to him afterwards and suggested he retitle his presentation "how to kill DC." That continues to be the case, given how Crystal City has just landed Amazon as a major tenant and Rosslyn has been landing corporate headquarters such as Nestle Foods.
Granted, you can argue that high occupancy tolls are a form of congestion charge. But some argue that the reason that Virginia made I-66 within the Beltway a toll road is to encourage businesses to relocate to Virginia from DC, thereby being able to get to and from a new location without tolls.
Alternative one: transit withholding tax. If the point of doing a congestion charge is raising funds, what I have recommended for years, but the federal government would have to agree, and it would be helpful for the suburbs to agree too, would be a transportation withholding tax.
It's done in France--providing a majority of the operating funding for transit service (France has successful light rail systems in many of its regional cities, not just in Paris), as well as certain areas of Oregon (Portland, Eugene), and for the MTA system in New York State (although I argue there it is too gross-grained, out-state residents served by railroads should pay less than core residents served by the subway--instead the same rate is assessed across the board).

Alternative two: commuter tunnel and transitway network. If the point of a congestion charge is interdicting nasty traffic, in addition to investing in more and better transit, I have argued for the creation of some roadway tunnels on commuter arteries, e.g., North Capitol-Blair Road, to shift commuter traffic away from surface streets, because it has deleterious impact on the quality of neighborhood life.
These would be covered by tolls, not unlike HOT lanes. Maybe they wouldn't fully pay their way, but by shifting through traffic away from neighborhoods, it could be a cost worth subsidizing.

The program should include dedicated transitways. DC will be testing some Downtown, and has implemented them on and off on 7th Street/Georgia Avenue NW. (Bus advocates in London argue that with dedicated transitways, bus throughput improvements would be even greater.)

-- "It's been a drawn out process, but DC is in the process of creating transitways on 16th Street NW," 2017
This program could also include some road decking, such as on North Capitol Street and the Southeast-Southwest Freeway.

I haven't written about it, but tunnelizing DC-295/The Anacostia Freeway, would be a boon to the quality of life and economic potential of a large section of the city East of the River.

This video by Bossi of DC 295 has unrelated sound. I'd turn it off before listening, unless you want to listen to an old Diane Rehm radio broadcast.
If we had true metropolitan transportation planning, the Maryland HOT lane study could be coordinated with a DC tunnel/decking study. For example commuter tunnels on 16th Street and Georgia Avenue would make sense to be integrated into the Maryland system.
