Spent a couple weeks at Bohuslan last year; brilliant crack climbing on great rock with short approaches, but don't remember much (if any) sport climbing - definitely wouldn't even consider it as a sport climbing venue.
Céüse - as others have said, will be hot and busy, and the easier sub 7a routes a bit on the polished side. And the walk-in is gruelling, unless you get up early. Guidebook suggests an hour - we found, even after stashing all our kit up there, pretty optimistic for the steep approach. There are heaps of great sport climbing areas throughout South France - Rockfax guides good to get some ideas of venues Haute Provence, Cote d"Azur or Languedoc-Roussillon are the three that spring to mind.
