There have been some really good, inspiring suggestions mentioned in previous posts but, given what you say about your experience and ability, I'd take them with a pinch of salt - at least initially.
Although there are people who've done the Walker Spur on their first trip to the Alps, they are few and very talented. For most of us, there's no shame in beginning at somewhere near the beginning and working up from there, partly because of the need to learn to negotiate alpine terrain safely and quickly, and partly because of the limited time we have to apply and consolidate what we're learning.
The voies normales on the Neige Cordier and on Les Agneaux in the Ecrins have been mentioned above and it is certainly a recommended area for learning the alpine ropes. However note that owing to changes to the glaciers and the routes are now graded considerably higher than in the AC guidebook. (F > ca. AD, iirc.)
The Saas valley is good too, but I'd suggest taking yourself up some easy snow plods in good conditions before doing the route on the Lagginhorn mentioned above. The summit slopes can be very icy, they are reasonably steep, and are very exposed, so they're not a place to be learning crampon technique. Stay safe, and have fun!
Edited to say I've just noticed that a lot of people in this thread are replying to someone named Jettison whose post I can't see and who seems to be different from the OP.
