Having just done something similar myself this month, I hope you get the same great weather that I enjoyed. I activated 3 alpine mountains - 2 in Germany and 1 in Austria.
Are you looking for “difficult” or easy mountains? Many (that are used in the ski season) have cable cars almost to the top, so if you want an easy enjoyable trip out, you can take the cable car, then walk out of and back into the activation area (note these can be different in different countries) or of course you could walk/climb from the valley to the peak if you are so inclined.
The advantage of the easy option is that the XYL / YL is more likely to come along.
I hope you will enjoy your SOTA-trip around the Alps in the same pleasure as I did mine in northern Spain und southern France during the last three weeks.
One of the activations was in Spain on EA3/LL-046 close to Pedraforca and two others in Massive Central in France.
I hope to meet you on qrg as chaser or by chance S2S
