I think A and C from your list are very important in books, and D supports A imo. I can do without super sophisticated world building (even a little inconsistency) as long as it doesn't detract from the story. No, I don't think those standards are too high, although I guess it might always be clear cut what is coherent/cohesive enough to pass muster.

Personally I would also add that the book should be well paced. I've read some novels recently that felt rushed at the beginning (not enough exposition) or at the end (not enough resolution), which made the whole thing feel half baked.

Do you think maybe the high concept queer fantasy novels you've been reviewing are written by relatively inexperienced authors? Since it is an emerging genre I'd expect the authorship to be on the young side, which means the writing may not be polished.
