Level1techs tends to go more into the enterprise server side but Wendell always has some gadget to show off.
I’d also advise to keep an out on the maker space, like raspberryPi or other SBCs, there are inexpensive machines and plenty of guides for various applications which don’t require much Linux knowledge if you’re already doing server stuff.

I’ve seen this recently - https://youtu.be/5ZQra087xOU?si=uJUaC1wv26z2Z7oB
Haven’t looked up a lot on this subject but have a look at https://pikvm.org/

I know there’s an answer but there are also inexpensive IP KVMs if you wanna go that route.

I would stick with SMB and SSH(SFTP). SMB for content sharing and accessible on any device like PCs or phones. SSH, which includes SFTP, for accessing everything else on the server.

+1 for bazzite. And OP had already worked with fedora

Fedora atomic (I’m using bazzite for gaming only) have Flatpaks enabled by default and are recommended, so it integrates well with the OS.
And seeing where the Linux community is going right now, Flatpak has been widely adopted by most distros which are not Debian based. There are ways to go regarding the packaging for the developers, but there are plenty of apps already on flathub. I’m using it on arch and bazzite and have no problems so far.
I can’t comment on the apps the OP requires

I haven’t noticed any issues. But only Plasma would be a DE. Qtile and hyprland are WM, not sure if that makes the difference.
Initially I had doubts if it would work, but so far so good.

Nice work. Why move from plasma to hyprland? Install both and login on the environment you want at any time. I have qtile, plasma and hyprland

I use it on my home server, TUI only, when I want to organise my files
