Except it's naive (at best) to expect a black man taking on the mantle of Captain America to not have racism be a significant aspect of the story.
And the Sokovia Accords weren't terribly interesting. Every plot point that pushes to the confrontations has pretty much nothing to do with the accords and everything to do with Zemo and Steve tossing out everything in the name of saving his friend. The accords give us two differing ideologies, but that conflict is barely explored. It's just how they justify who is on which side of the airplane fight (kind of, since Spider-man probably knew absolutely nothing about them).
Regarding Steve - if he was really supposed to be F the government, it should have been him vs. SHIELD in Winter Soldier and not him vs Hydra. Him not signing the accords in Civil War maybe hints at him being "F the government" but it's nowhere near potent enough to suggest that was his shtick.
