I would recommend a trip up to Dorgali, this is a great crag up to 7a, not majorly impressive but nice enough, try Overland (ok so it is 7a+, but soft and sounds like it would be one for the missus and not you).
Cala Gonone and Cala Luna are musts. There is loads there. A day at Cala Luna is amazing. Short and intense routes in paradise. The other must is Millenium Cave just outside Cala Gonone, a couple of cracking 7a's in there in a stunning venue, tricky to find, use the new guide you can buy in Cala Gonone.
The best 7a we did was actually in Cala Fuilli, called Capucetto Rosso. Slightly overhanging, juggy and delicate at times, it'll suit you both. Nice little gorge that place.
Have fun!
