I mean, yeah, but nobody really uses Debian (or Arch) until they know what they're doing. Distro hoppers start with Ubuntu because it's popular, then hop to Mint because it looks more like Windows (no disrespect intended toward Mint or KDE), then they go back to Windows until Microslop pisses them off again, then they try Fedora... that was basically my journey through Linux as well.
Having been a Mac user for 3 years, I feel like I'd do better with Linux. If I ever get an old PC — one of my nerd fantasies is to "rescue" an 8th gen/later i5 workstation with 16GB RAM (maybe even 8) with the hard drive taken out (corporate secrets and whatnot), and I put a SATA SSD in there and put Linux on it. It's not that expensive to do all that, but I don't really have the room. I can also stick it in a corner somewhere and run it headless. I know that macOS is "certified UNIX" and I know enough to know that this is a mostly disingenuous statement, though I'm not well versed on the details. I do know you can do a lot more with macOS with the command line though, because macOS is built upon OS X, which was built upon NeXTStep, which was built upon UNIX. So the guts are still kinda there and you can do a lot with it. I actually prefer to use brew to install stuff, it's a lot faster than going through the GUI. The site just gives me the name, I ⌘+Space, start typing Terminal (all I need is TER), hit Enter, "brew install" then whatever, and it installs the dependencies I don't have, updates the ones I do, then installs the package and it just works. But anyway, all that aside, I'd just remote into it and run it as a server. Next step would be a NAS to take my Plex server to the next level. It runs fine on my Mac, but I think it would be better running on its own system.
