For remote desktop you could try TeamViewer
Edit: Also, Thunderbird isn’t amazing imho. I would also look at Betterbird. Much better :o)
Mint is a safe bet, I would also suggest you have a look at Pop! OS and CachyOS once you feel a bit more comfortable with Linux and are curious at all. They have a bit more cool stuff to offer that you don’t really get from windows imho
Not sure if I misremember but I think the Mint software manager has a menu option somewhere that shows you a list of Papas you’ve added
You could try CachyOS, arch based and you can run it with KDE. I use Pop!OS and have been super happy with it
Deluge and Surfshark VPN
I just don’t like KDE and am not a big fan of stock Gnome either but the PopOS version with COSMIC features plus the Dash to Panel extension make it pretty useable
