It depends what your long term goals are. If it’s just to run those services as simply as possible, then just run them in docker on windows. If you want to learn Linux, then setup you other hardware and install a server distro. Ubuntu is fine, but I use Debian.
Then once you get used to Linux, one day you could migrate your Plex server to Linux and remove windows from your main server.

Non, I use Linux purely at home. Have no way to use it in the heavily regulated world I work which is very corporate and very locked down windows where I cant even access CMD or pin things to the taskbar.
But at home I run Debian and raspberry pi os on my 2 servers, and arch Linux on my desktop, and Debian with retropie and cinnamon on my laptop.
I have no interest in distro wars, no distro is better than any other, they just all cater to different subset of people and users. I don’t even believe Linux is superior to any other os. I love Linux, and it is perfect for me, but I would never advise my wife to try it, as it offers nothing she would benefit from over her current use of windows.
And I develop and maintain a package in the aur, but it is minimal, and I have published on GitHub a couple of apps, but I would not describe myself as a developer or maintainer, as they are just tiny personal fun projects.
And finally I am a huge proponent of foss and anti big tech where I can be. I believe I currently have all the benefit of the android ecosystem without using it at all. As in everything is backed up and synced to the cloud, but I own my cloud. Everything except Lemmy and email I self host. Calender, contacts, files, photos, music, DNS, search, pdf editor, notes… That’s all I can think of for now.
