@silhelm Jemisin isn't known for feel-good stories necessarily, but The Hundred Thousand Kingdoms is excellent all the same, and not nearly a downer on the level of the Broken Earth trilogy.
Leckie's stuff (Ancillary Justice and sequels) is great as well imo, though YMMV on whether you think it breaks out of whiteness despite most characters being described as some flavour of dark-skinned. Likewise the Murderbot Diaries by Martha Wells.
The Jasmine Throne was great and queer, but not feelgood
