You can also delegate a subdomain to another provider with an API, but yes I see what you mean. Although I feel like getting port 80 open would be difficult as well in those situations.

It does but it's a bit of a weird way of doing things.
I'd say they're actually easier, at least in my experience. Since wildcard certs use DNS-01 verification with an API, you don't need to deal with exposing port 80 directly to the internet.
You shouldn't have the do anything specific at all, local network stuff works without internet and Jellyfin doesn't rely on any internet servers like Plex does for authentication.
There isn't a full alternative, but if you just want text chat with some voice chat added on there are options like Matrix.
How would I join a community without knowing anyone with that setup?
I just do full system images for that reason, easier than trying to pick and choose what should be backed up. Used to use Veeam, currently using Synology Active Backup.
For online backups I don't due to size, but for local backups it's just way easier.
No ads on YT with Firefox + uBlock, not sure why your setup isn't working.
What's the alternative though, we have Chrome and Firefox as choices. Chrome is far worse than some issues with Firefox around CEO pay.
To install at minimum you'll need to likely shrink existing partitions and create new ones for linux if you don't want to wipe the drive, that would be a dual-boot setup with Windows still installed along side. Or you can just wipe the drive entirely and have only Linux.
Regarding the files you should already have backups of anything important, if you don't, set it up ASAP.
Messing with partitions can easily cause data loss if something goes wrong.
You also never know when hardware failure, malware, power surges, lightning strikes, or whatever other disaster will happen and cause data loss. 1 copy of files might as well be 0 copies.
It's a public site that'll be backed up regularly, what kind of important data would you be putting out publicly?
Cloud storage? Store it on 2 different providers like B2 and iDrive or something, pretty low complexity.
