Digging through my shelf for ones you haven't read...... You've read the only really good ones I've read, but if you want a few that were okay just for research, let me know (I know you like reading mediocre books to see what's been written before, and to learn from what you dislike).
I have one good one, though - you should read Bella at Midnight! It's not my favorite ever, and it's not amazing like a lot of books. But it's a VERY sweet and unique retelling based on Cinderella. The retelling aspect is very light, and easy to miss if you don't know it's Cinderella, but I actually like that about it. It's the sort of book you would enjoy.
