I made a doc that helps you find games and other stuff in the itch.io bundle for racial justice and equality.
The doc has lists of games that meet certain accessibility requirements (blind-friendly, etc) or not (warnings about games that have especially bad flashing lights). It also has lists of games with various kinds of representation (POC, WLW, trans, etc). And then it has some lists of some other interesting kinds of content (educational, self care, etc). It's a work in progress, but it has a lot already!
Read it here, and comment with stuff to add: https://docs.google.com/document/d/11eKwMOMPoTMIx6D5-Cv-YRHtEGyaiWQ-20BzDDa5SM4/edit?usp=sharing
