If you haven’t already read all of Becky Chambers’ books, highly recommend all of them. The Long Way to a Small Angry Planet is pretty well known, but her new novella miniseries (Monk and Robot) is great as well and features a non-binary main character which I don’t see all that often.
Books
I love everything I've read of Becky Chambers, it's like a warm hug in book form. I want to be Dex when I grow up!
Choosing a theme by month is a really great idea, that would probably help me with planning out my giant TBR list.
For Pride month, I started Can't Spell Treason without Tea by Rebecca Thorne. The blurb that caught me was: "...a cozy tale of mishaps, mysteries, and a murderous queen throwing the realm’s biggest temper tantrum. In a story brimming with hurt/comfort and quiet fireside conversations, these two women will discover just what they mean to each other… and the world."
Also I'm going to read Loveless by Alice Oseman to get more exposure to ace/aro perspectives.
In short fiction I recommend Sam J Miller's "The Heat Of Us: Notes Toward An Oral History" which is about the Stonewall Riots but adds a fantasy twist. I don't think the twist is necessary, but Miller's description of the events is so lucid and engrossing that it's a substantive tribute.
