I’ll second Jemisin and Roanhorse. Jemisin in particular is a damn fine author, and it wouldn’t surprise me if the Broken Earth ends up joining things like The Dispossessed in the literary SF canon.
This only sort of fits SF and Diverse, but Alex White’s A Big Ship at the End of the Universe is probably the best “pew pew space opera” I’ve read in forever. The gunfights are great, the space battles are great, and it seethes with anger at the privilege and powerful. The sequel is pretty good as well.
Becky Chambers has blown up recently, so you’ve maybe heard of her works, but if soft and kind SF is your sort of thing you’ll absolutely love her. the long way to an angry planet is an almost required intro book, but the real gut punch winner was record of a spaceborn few. Next to nothing happens, but damn was it incredible.
If you’re looking for some old school transhumanist hard SF, Linda Nagata has you covered. Check out Edges.
On the other hand, if you’re looking for some pure fantasy featuring some of the best writing in the genre I’ve ever seen, check out Sofia Samatar’s A Stranger in Olondria, probably the most beautiful novel I’ve ever read. It hit me hard, and I really don’t know why, and all I can say is that it’s absolutely amazing.
