Either way, I think that DC is better off now than it would have been if the freeway plan were fully developed. Had the freeway system been built, then I think that traffic problems in the District would be worse, mixing freeways with DC's road network would be a mess.

Every driving experience I've had in the DC area clearly proves otherwise.

The only way your idea would be the case, D-Dey, is in a no-growth, no-inducement scenario.  History and reality have proven that such a scenario really doesn't exist.

I wonder how the planned DC system would work if built today as a network of 4 lane HOT facilities.

Would likely have an insanely high toll and earn the moniker of "Lexus Lanes" used elsewhere…

We may yet find out.  In particular, if D.C. wants to toll the four-lane section of D.C. 295, where demand during peak commute times and frequently on weekends is far above capacity.

It would have been a lot better had they built it out this way:

By failing to have any interstate actually run THROUGH the city as I-95 would, congestion was increased on the capital beltway.
Moreover, not building I-266/I70S made it much harder to get into DC, which if built, would have increased the accessibility/attractivness of DC vs. the Beltway for business.

Also, most of I-66 in DC and I-95 would have been tunnels or cut and cover, minimally disrupting the neighborhoods.
This was short sided and is a big reason why the area has such bad traffic.
