Honestly I skipped most of the Cap stuff because it’s a bit whatever, think the only thing I’m really missing for context is Civil War but there’s a one line summary of it in Infinity War/End Game that caught me up more or less well enough.
I’m also skipping Tom Holland as Spiderman because Miles Morales is MY Spiderman, and Black Widow because I’m going to assume it’s Scarlett Johansson’s Bum: The Movie, and I’ve already seen that one when it was called Ghost In The Shell
This is the real genius of the MCU for me, you don’t really need to actually watch a lot of it, they give you enough context to enjoy the various thing without it seeming like "previously on the MCU
Think I’d only seen about half the films leading up to Infinity War beforehand, but it made perfect sense
