Recs if you like The Name of All Things...

This is NOT for books featuring trans or nonbinary protagonists in worlds with gender systems that mimic modern real-world ones. This is for books like Left Hand of Darkness or the Imperial Radch series, where the setting has an invented system of gender and/or sex, or of assigning gender/sex. I'm including interesting-to-me matriarchies (so, not ones that are just our patriarchy but gender-swapped) and gender systems that include male and female but have other genders/sexes too.

Suggestions are extremely welcome!
