I’ve got nothing for you on Italy. I can only give a little on the 4Vallées in the Valais region, based on being there 19-26Feb. You definitely want altitude. There wasn’t a lot of snow, but there was enough. Esp if you went back country. The big issue was the warmth. I used spring gloves the whole week. Cold would be -4 to -6, maybe even -8C, but that’s 3000m. Down at 1000-1500m, it could go from 0 to +11C, depending on day and time. But there really wasn’t slush/corn snow unless pretty low, and in the sun. However, refrozen even up 2000-2500m could be a problem.
At the time, it didn’t look like enough snow on the Bec des Rosses to hold the FWT finals, but there was over a month to go, and that's a lot of rock to cover.
Looking off the backside of Mt Fort, there looks like there’s enough snow for decent touring. The sun is the big factor.
It did get colder the day we left. I also talked with a guy in the airport who did heli touring out of Verbier,(flying from Savoleyeres). They had some good stuff, but sometimes skinning up in the heat was rough.

Looking down from the near side tram deck above^. There should not be moguls like that.
Unfortunately, I didn’t get a shot off the backside.
