Am I making a mistake by having my Jellyfin server proxied through nginx? The other service I set up did need to be public so I just copied the same thing when I set up Jellyfin but is that a liability even with a password to access?

Not sure about the other but PoppinKREAM became known on Reddit during the Mueller probe for very long, very well researched and cited comments mostly related to politics. Their citation style in particular meant their comments got tons of Reddit awards and were highly visible.

You are probably lucky, for now. I’m pretty sure they are rolling it out in waves. Boiling the frog and all that.
