Binti is mostly about conflict with tribes in Africa and species so that might fit the bill for your black sci fi, at least the starting novella. I stopped reading Kindred because I was overwhelmed with the trauma she suffers in slavery times when she inhabits the body of her ancestor - the encounters got worse and worse.

There's also Dahlgren-17 post apocalypse that has some race stuff in it but not black trauma at all and is more about sex because IIRC the writer is working through some experiments with language and his own sexuality/experiences in it, I think it has the most by quantity and detail sex scenes i've ever encountered in a book and it felt repetitious by the end because some of the encounters felt like the same actions again and again.
