With a machine like that, you're firmly in the mainstream of linux. Almost any distro will run well on it, so selection is a matter of taste.
Debian is a solid, conservative option, though they have a reputation of lagging behind other distros in terms of software versions. I do like arch, their wiki is first rate. It has the reputation of being finicky but I've always found it pretty straightforward. Great for the extensive docs and not trying to insulate you from the system.
I personally would avoid ubuntu these days, they seem to be leaning into the Ubuntu Way for things like installing software. A bit lock-in ish for me.
FWIW I'm running nixos on my thinkpads, works great. Nixos is not to be undertaken lightly, there's a lot to learn and docs are meh. Stability is second to none, and the declarative configuration management makes it great for easing into devops.
people performatively declaring they are going to Linux doesn't bother me at all. its good press, builds its reputation. people try new things for deep reasons sometimes, but also for casual curiosity and fashion following, and that's ok.
