Signal is probably your best bet for a solid user-friendly (and privacy respecting) experience with calls. Matrix/element is another decent option (its federated like lemmy and mastodon) but a bit less intuitive.
I can highly recommend this! The switches are very cheap and I love my silent G305. The hardest part was probably the middle click button but you can skip that one if you don't care about it as much. While you're inside, you could clean the scroll wheel which might fix your swelling problem.

I am not very skilled with solder and found it very easy. You don't need anything fancy like a desoldering gun. Just a regular soldering iron with some solder and flux worked for me.
