Here's a tricky question - what operating system should I choose?

I have somewhat conflicting requirements: I want to have a small portable "media & services" device, ideally not much bigger than a phone, that's easy to connect to a local network over ethernet or wifi.

This device then starts acting as shared drive/storage, so I can easily read and upload files to it from my laptops and (maybe) access it from my phones. At the same time when I connect this device over HDMI to a TV I want to have a reasonable media browser and a player (movies, shows, maybe music, podcasts), for plus points controlled with TV remote. I don't care much about data reliability, almost all this is media that I can try downloading again later. Optional: It would be great if it's easy to run some services from this as well, like pi-hole.

Most of the time it would be connected to a home network, but I'd grab it when I travel and then connect it in whatever hotel or a place to a TV and have access to my media and files.

So my current setup is that I have MeLE Quieter 3C with 16GB RAM, I put a 2TB M.2 SSD in it (and another 1TB microSD just as a storage expansion for files I don't care about accessing fast).

And now the question is which system should I put on it? Essentially should I do something like TrueNAS, or something like Umbrel, or Proxmox or just run bare Debian on it? Or something else? How stupid and wrong am I?
