In reply to von_donsburg:
Having reread your post more attentively, I would stick to Alison Rib. Wicca is on a fairly isolated part of coast, and though you can park at Wicca Farm, it's not straightforward how to get to Wicca Cliff. Then you've got to get down (and back up) a steep and broken hill to the Pillar itself. Carnelloe I wouldn't bother with.
Bosigran is a nice and easy drive from St Ives for your long-suffering partner. Short and easy walk-in and all the atmosphere of a sea cliff but without the access challenges. Porthgwarra, where you'd park for Chair Ladder and Carn Barra, can be a nightmare drive in the summer traffic.
Halladrine is a nice little crag with easy routes, but it's a further and steeper walk down to the shoreline, and getting to the base of the routes requires a bit of scrambling above the tide line so can be affected by the state of the sea.
Hope you enjoy your trip and are able to get back to a bit of climbing.
