In reply to An Triubhas: You might consider the Oberland. Plenty of routes that fit your bill, both on the 4,000 metre peaks (the Jungfrau, Finsteraarhorn and Aletschhorn might be good choices when you are acclimatised) and the lower ones: try the Doldenhorn, Sustenhorn, the rock peaks around the Mittelaletsch hit, etc etc. Plus load of great rock climbing at Fisch, Grimsel, Salbit and Handegg.
