Docker vs ... not?

I’m pretty new to self-hosting in general, so I’m sorry if I’m not using correct terminology or if this is a dumb question.

I did a big archival project last year, and ripped all 700 or so DVDs/Blu-rays I own. Ngl, I had originally planned on just having them all in a big media folder and picking out whatever I wanted to watch that way. Fortunately, I discovered Jellyfin, and went with that instead.

So I bought a mini pc to run Ubuntu server on, and I just installed Jellyfin directly there. Eventually I decided to try hosting a few other services (like Home Assistant and BookLore (R.I.P.)), which I did through Docker.

So I’m wondering, should I be running Jellyfin through Docker as well? Are there advantages to running Jellyfin through Docker as opposed to installed directly on the server? Would transitioning my Jellyfin instance to Docker be a complicated process (bearing in mind that I’m new and dumb)?

Thanks for any assistance.
