I've had the odd day at some places in Ariege.
Calames has the range of grades you are after but is south facing, shadeless, and was warm in October. Pilier des Cathares was a very pleasant 7 pitches of bumbly 6a. Johnnie Walker was my friend's first 8a and it took her a morning's work so is presumably not too hard for the grade (said friend should have climbed 8a several years previously but it was an unusual event for a Brit. woman in the 90s).
Auzat is great up to about 6c: lovely slabby, fine-grained granite, usually very well bolted. There are plenty of trees and some of it is east facing, so there should be some shade in the afternoon. I don't think there is much harder stuff though.
