In a word - yes - i3 is incredibly productive and customizable, but it's not for everyone. I've been using i3 with no DE or DM for about a decade. Every time I try to use a full DE like KDE, Gnome, etc, it's just so slow and bloated, and gets in the way. And there's 100's of extra packages that get installed, and be updated, that I don't use. I don't need anything but terminals (of which I have about 40 open in 12 different virtual desktops), a browser, and an editor when vim isn't enough. So for me, it's perfect and simple. I don't know what will happen when Wayland finally wins, but that's 5-10 years away before it really wins.

Yes, i3 is not automatic, but you can arrange things however you want - it's definitely something where you need to read the docs first.
YouTube links are fine - I hate those stupid bots that spam posts about such links.
Pretty much everything that's running on a microprocessor (i.e. larger than a microcontroller) and not from Microsoft or Apple.
Profiles work fine, but you might have to set things up initially with working Internet. No idea about watch lists or parental controls though - we don't use them.
Neither of these points are entirely correct.
While remote authentication is the default, you can configure Plex to not require any sort of auth at all for local users. That's how mine is setup, and we can watch content around the house even when our ISP is offline.
I also don't get ads or anything else pushing other content - I only ever see my own. You just have to not show those things in the sidebar. So again, the defaults can be changed.
Definitely worth trying Jellyfin if it works for a particular case. I've tried Jellyfin, Emby, and Plex - but only found the latter to be reliable enough for OTA DVR via an HDHomeRun which is our primary use case.
Your root filesystem is NTFS? That's likely the problem - I'm surprised it boots at all. Switching to a Linux filesystem is the likely solution. You could also try a newer kernel, too - 5.10 is quite old, current LTS is 6.1. Good luck.
It's a good question - I don't know, because I haven't used it. If it's 100% compatible with i3 down to its configuration and features, then sure, it's palatable.
