I’m in the same boat as you and never found anything for Samsung tizen os. Smarttube is android based only and anything streamed to a Chromecast still has ads.
Edit: okay I thought let’s search one’s more. And there is tizentube did not try it yet but seems promising
I use ardour as DAW, but only for recording on Linux. It’s also available for macOS and windows. So you can check if it fits your work flow.
I mostly only use Linux, but sometimes you just need a program with out support. In my case it’s sometimes qlab, Linux show player is great(and I have used it for many shows). But it’s not feature compatibel with qlab
Even if something like proxmox or a Debian install with docker is more customizable. It’s a steep learning curve.
But isn’t something like truenas scale a option? I run Emby(as my media Server) and the arr’s on it. All the apps are already in the “software store” including plex. And setup of the arr’s is just the same as normal. All installs are basically automatic.
I easy passthrough my intel gpu in the config page on the webportaal, but don’t how easy it is for Nvidia or amd. Especially with Nvidia due to drivers. But maybe someone here knows?
I work as a theatre tech (light and sound) at a college(theatre arts department). I do however use Linux and made some scripts in Python to control my ligtdesk and sound table. So a bit of IT related work. But also talk with students about the creative part of lights, sound and projection and how they can use it during and after there study in there shows.
I also do some shows for them in the small Theatre in the college and outside the college.
And give them a workshop teaching them the basics and how they can tell to a tech what they want and how they can do somethings themselves.
For getting a idea of how your games run check out protondb.com you can add your steam library to easily check your library.
For epic, gog and Amazon prime gaming you got heroic (https://heroicgameslauncher.com/) it also uses proton to play windows games.
GPU drivers are fine. AMD just works for gaming and Nvidia (depending on distro you need to install the drivers, search how to install them and dont install them from the Nvidia website) works fine if you just have a simple setup. The Nvidia drivers are improving alot by the way.
Random mouse, keyboard and other stuff is a hot or miss. Most of the time basic stuff simply works, but maybe there are no drivers/programma to set rgb or macros. (P.s. Try open rgb for rgb stuff)
You can always try with a dual boot. If you not used to Linux and like gaming maybe something like pop os
