@tihyltew hmmm...
I'm not #ActuallyAutistic but am adjacent; I also had somewhat mixed feelings about this series, but the "Last Pick" graphic novels feature an autistic main character and a disability justice implicit framing. They're probably not what you're looking for exactly (certainly they're fiction meant to entertain, not educational), but I didn't see any other replies yet so I thought they might be worth mentioning. In the same vein of fiction, "To a Darker Shore" by Leanne Schwartz felt kinda nice even though I had some nits to pick with the details of the world building, I thought that the portrayal of both of the autistic main characters was good.
Sorry that I don't have any non-fiction recs nor better fictional ones. The few other fiction books with autistic characters I've read are ones where I'm not sure I feel good enough about their portrayal to recommend them to others (Last Pick is honestly borderline...). For example, I just read a sorry story in LeGuin's "Searoad" focusing on a probably-autistic character, but even though it fit nicely into the full book as a whole, on its own it felt kinda "meh." Elizabeth Moon has a novel with an autistic main character that I enjoyed, but that one I know is not #OwnVoices and I'm not sure his much of might resonate or feel patronizing/harmful to an #ActuallyAutistic person.
I too would love to read something with a disability justice lens from an autistic standpoint.
