There's an interesting series of fantasy novels by the author Graydon Saunders, occasionally recommended on this website, that almost entirely avoids the use of pronouns: https://www.goodreads.com/series/242525-commonweal . The avoidance of pronouns is a stylistic choice, but not a didactic one—you might not even realize it until you're a third of the way through the book and you start questioning whether a character you'd imagined as male or female might actually be a different gender, or not gendered at all. It's interesting to see how the author achieves this in dense but readable prose, without drawing attention to it.

Ancillary Justice is told from the point of view of a character of a culture that doesn't draw the distinction in language. It is occasionally remarked on, but generally from the point of view of the main character being always a bit paranoid that they'll cause offense by not referring to characters of other cultures and languages correctly.
