Two days will require skipping a good number of things... or doing COVID schedule where they don't have most of their entertainment.
It almost is all of WDW in a fraction of the space when it comes to attractions and nighttime entertainment. Spend 3 days or prepare for full commando mode.
There are a lot of attractions I'm okay skipping -- there's almost nothing I care about doing in DCA beyond RSR and Soarin', but I'd only do the latter if it's Soarin' Over California instead of the world. Grizzly River Run is the only other ride in that park I'm interested in, but wouldn't be upset if I missed it.
I think I'd try to do a few hours at DCA one day to just walk around and see it along with those two or three rides (hopefully) and then spend the rest of that day and one other full day at Disneyland. As long as I can get in the Fantasyland dark rides, POTC, and Indy at DL proper I'd probably be happy, although there are several other things I would really like to do. Most everything else is stuff I wouldn't really be upset if I missed, even if I'd ideally like to do/see it.
