IMO debian and unbutu and the projects based on them such as mint are the most supported though the community with a lot of places to look for help.
CentOS and it's forks tend to be more stable (not always but tend to be)
And FreeBSD is a royal pain in the ass, but once you get it up it's rock solid and secure.
But, for something like this. If you install one and it does not work for you, just move to the next. You don't have to live with any particular distro if it's not working the way you want it to.

But it is not as bad as it was 15-20 years ago. I recently installed it on my laptop, without too many issues.
Can run as a workstation (Xfce/Plasma, native Firefox/Chromium, Office, and 40k+ native apps or
WINE, Linux compatibility. etc). Or run it as a firewall, router, mail server etc.
PF on it just blows IPTables out of water. pkg installer is awesome.
If you want, you can slim it down, compile for your particular hardware.
I am really impressed by how much it has improved. I am switching all my machines to freeBSD.
PS. I am done playing with blocking/patching Windows, or deciding which Linux distro is the 'best'.
FreeBSD is the best, end of story.
