what do you think about:. "you don't need to choose one" and "you don't need other people to choose for you" and "distro isn't that important in many cases"

I can agree 100% on what distros I use for what types of computer. And I can agree 100% on what I'd have used now, if i were a beginner again.

But all i can recommend to a stranger is, backup all your stuff properly,

try a few out (v.m. or liveCD/Ventoy) and be prepared to change.
make sure to check application versions in the base software repository - for any programs where that matters to you. and ease of updating - if that matters to you. and check out some flatpak if you think that might be a useful way to get extra applications or in some cases up to date.

if in doubt, choose gentoo /s
