Let's say I'm willing to trade faster delivery for lower cost - is there another site with similar selection that you would recommend?
I ordered some common 1/4-20 bolts from McMaster recently because buying them from the local big-box is an even worse deal, but I did feel like I could get a better price somewhere else.

The server certainly should have picked up the change in metadata but I can't help you with why it didn't.
I can suggest that you edit the metadata in Jellyfin rather than using external tools and moving items in and out of the library. Just click the three-dot menu for a track or album and choose "Edit metadata". If it doesn't pick up changes made from Jellyfin then something is very wrong.

If you can avoid having you server and the media library on separate systems you should. That means buying (or I suppose building, but I wouldn't recommend it) a NAS with sufficient processing ability to stream / transcode as much as you need, or stuffing a lot of storage into your mini PC.
One of the problems you'll run into if you use separate systems is that it's non-trivial to get the server to automatically notice new items in the media library and update to include them. I'm sure there are others.

Ah, okay. I'll hold off on updating then (I think I'm using native mode, but I can't remember).

So this WON'T break the "Jellyfin" Kodi plugin? Just making sure it's not the same thing as "Jellyfin4Kodi".

Well that's a shame. I'm sort of half-assedly using syncthing to backup my photos from my phone to my server, but mostly I rely on immich. I never really got the hang of using syncthing with my phone.

I'll second Tyranny and Pillars 2.
Tyranny's ending is... well... they tacked on some text - but it's a great game otherwise.
PoE2 is more enjoyable than the first one, IMO, just for the lighter tone. They do a better job of explaining the world, too, because you aren't bludgeoned with lore-dumps like in 1.

The only console I ever spent a lot of time with was the NES, so I'm not at all native to the modern XBox / Play Station controller with its 166 buttons. But I know that some games are best with a controller, so I bought a Steam Controller and an XBox controller. I made it most of the way through Nier Automata with the Steam Controller, but I put the game down for some reason or another. I also gave Hades (what I think was) a good effort, but I never made it out and I stopped caring.
The only game I've completed with a controller is Brothers: A Tale of Two Sons, which you really shouldn't play with m+k, if it's even possible. I'd never try to play an FPS with a controller.

Lol, I still check out slashdot too - although it's usually a day late with news and the comments aren't anything special. Force of habit I guess.

Wow, that takes me back. I used to prefer Anandtech to Ars Technica, Hot Hardware, Tom's Hardware, etc.
But I haven't visited any of them in like a decade, so I can see why they might be shutting down.

Masochism, paranoia.

Another vote for Debian, and I'll suggest you go ahead and install Jellyfin directly rather than messing with Docker.
https://jellyfin.org/downloads/server
I'd been running JF under Docker on my NAS, but when I moved to a new server I decided to just install it directly and it hasn't been any problem at all. You'll get a notification when it needs to be updated and it's just a few clicks to do so. You won't have to fight with Docker to get hardware acceleration working - which isn't to say it won't be a PITA, but it's one less layer of complication.
