ahh, i was just going to mention Left Hand Of Darkness here!
& yes, the main culture/language in Ancillary Justice, the Radch/Radchaai, is pretty much culturally agender; Radchaai (the language) doesn't really have gendered pronouns and the Radchaai culture doesn't really acknowledge gender as A Thing that matters. (Though the book itself does this by using she/her pronouns for everyone, but in-universe the Radchaai language isn't gendered, iirc). There's a bit in the first book where the main character is having difficulty speaking in a non-Radchaai language because the other language does have gendered pronouns/verbs, and the MC has some difficulty identifying which pronouns to use for which people.
