I struggle to find good blind representation as well, but for disabilities you could try: the young elites, features a partially blind protagonist, a curse so dark and lonely, character has cerebral palsy, the diviners. For the last book, you won’t meet the disabled character for a bit and I don’t wanna spoil too much. I will let you know if I think of any others. These are all young adult/fantasy but exceptional ones in my opinion.

“Dog Driven” by Terry Lynn Johnson. No, it’s it’s not about a guide dog. At least not in the traditional VI guide dog.
