My wife has a T480s on standard 2022 LTS Ubuntu, it is a machine old enough to not need the latest edgy mint ; a friend of mine has had to install it on his 2023 X1 tho.
Standard Mint will do fine. Default DE is boring as hell, be sure to look at others like Gnome. I love Gnome.
Also, using “live” USB keys OP can try several distros and check what they find more attractive in the default state of a distro.
PopOS, Elementary, Fedora, Tumbleweed… So many of them.
I say Tumbleweed is best because of the perfect, seamless integration of BTRFS / Snapshotting / Rollback system. It is truly the best way to dip your feet into Linux and get it back working in a single click when you (inevitably) fuck up.
