I’ve been using Fedora for years across several devices. I’ve only seen my device compatibility improve over the last few releases. For example, my HP Victus laptop’s camera would work but not the mic, this has been fixed. My desktop runs several monitors with no issues and keyboard shortcuts have never done anything goofy. It is my preferred distro so I am biased but I’ve used a lot of others and I think Fedora is one of the more consistently good distros.

I use it in truenas with no issues. Might be worth it to spin up a vm and run it that way.

GrapheneOS works well. But only on pixel devices.

Atuin Magic Shell History is pretty good.

If you’re looking for a wide range of games tested, NizVicious. FreddysGamingBenchmark focuses on the steam deck. EtaPrime usually test all his builds in linux at some point but it’s mostly the same games as he’s a hardware channel (newer titles get added though).

Unless the info is out of date (which is likely) kern.log syslog or messeges.

Have you checked the logs in /var/logs?

Watch a truenas setup for it snd compare the permissions maybe? I got it working on my truenas server but it takes a long time to spin up so it seemed borked but was just slow to start. Not directly comparable, I know, but any port in a storm.
