A while back, somewhere around Linux 5.17, some Intel chips in laptops caused the Linux kernal to rapidly set backlight brightness to 100% then zero. This flashing would likely cause it to break. That’s the last one I remember only a year or so ago.
This only effected arch an it’s varients to my knowledge though, as they were the first to recieve the update, and it was fixed very quickly. To my knowledge nobodies systems were broken from this.
Of course there’s the suggestion of installing KDE plasma on PopOS! Which will work quite well but to give some info on the others:
KDE neon is mostly for devs and is less well maintained than other distros. Still definitly not a bad choice.
Tumbleweed stronk. Definitly out of what you say my preference though yes, it’s not deb based. You should be able to get what you want though through the app store and the open build service. Really it’s discouraged to find random .debs online and install but OpenSUSE runs on .rpm which are fairly commom.
Kubuntu is also good. Last time I checked it’s a bit slower moving than pop but that’s not inherently bad. Definitly a great “It-just-works” distro. Some people, myself included, dislike snaps which are built in but if you don’t know what they are I doubt you’ll care. Most of the hate is overblown.
I’d caution against endeavor as it’s arch based. It’ll demand more from you, stuff will definitly not just work all the time,and if an issue arises it’ll be the first to catch it. Like the grub rescue error that showed up about a year or so ago.
Don’t use Manjaro. The devs are incompetent and destructive to the ecosystem.
Debian is also chill. There’s always unstable (can’t remember the current name. Debian Trixie?) For something that’s more up to date
Last thing no matter what distro, just like an exe, a .deb is just an archival format like .zip and can be taken apart to be manually installed. I understand not wanting to do this though lol and it’s not always that simple
