It has several unsecured endpoints.

If you read the comments the devs know it's a serious issue but don't want to break backwards compatibility fixing them. Their solution for now is to warn people of the risks of exposing their instance to the Web. Which I don't think they're doing a great job of.
Aside from most of those being “potential issues”, which weren’t proven, the rest are GETs of things that do not need to be secret, things like album art and list of installed plugins. Besides the one plugin issue, which was an actual security issue, which was fixed over a year and a half ago. https://github.com/jellyfin/jellyfin/pull/11436
Contrast that with Plex which has numerous high severity CVEs that include things like remote code execution, directory traversal, and more.
Yeah, as you said, that's a pretty serious security issue. That's a data leak that explicitly lays out the shape of your attack surface. It tells the attacker exactly what additional software your server is running and if any of it includes known vulnerabilities, the attacker now knows how to gain access.
That only works if the plugins are somehow accessible through an api controller, which as far as I’m aware, is not how jellyfin plugins work. So no, it wouldn’t increase your attack surface at all.
