Haven't had experience with most of those and most of my cacti grow outside but sheltered from rain. You live in italy so your weather is close to ours. Your safest bet would be opuntia ficus indica, agave americana, agave desmettiana, agave attenuata (although not sure it could handle 20F but can handle the winter rain), sedums, sempervivums, golden barrel, hylocereus undatus, euphorbia candelabrum, cereus peruvianus, stenocereus marginatus, opuntia humifusa... these can stand the winter rain here (most are at low altitude)
However, it all comes down to your soil and how much precipitation occurs in winter. A raised bed is a good idea

You can give us more context. Is the garden gonna be in the ground or on a roof or something similar? How much precipitation do you get? Is hail a problem?
There's also euphorbia neriifolia

My zone is very rainy and windy, in winter usually we have snowfalls. The garden is in the ground in full sun.
i have seen a lot of Trichocereus schickendantzii in this zone and all are planted in the ground.
I love san pedro cactus, I hope it will survive here.

If you want to plant in the ground it's a good idea to mound the cacti you wanna plant. That means sort of making a small hill of free draining material and planting the cacti, or making a raised bed of free draining material. If you want to plant directly in the ground, dig a hole at least 3-4 times larger than the root ball and fill it with a fast draining medium.
San pedro cactus...not a good idea IMO. My grandfather had a large one until most of it was chopped away one night. They think the San Pedro has magical properties...such a shame. So if you don't want to risk someone stealing your cactus, stay away from San Pedro.
