I have a developmentally disabled family member who would love all the content on my Jellyfin server. I worry that they would also click each and every option in the settings and they may struggle if navigating to the content is too complex. Picture someone who does not understand how Facebook works, but has created 20+ profiles and has 5-10 google accounts because their favorite YouTube got banned and they don't understand that it's not something wrong with the account. :-D LG WebOS is probably too cluttered and chaotic for them and they wouldn't be able to tell the sponsored/pushed content apart from our self-hosted stuff and would probably just add Prime video and try to rent the same movies they already own over and over again. :-/ I have a Shield on my partner and I's main TV and while it is way more logical and easy to use than LGs webOS or any of the stuff like that, it might be too much.

What I'm looking for is some kind of streaming stick or Jellyfin capable solution that is as simple and easy to use as possible.

Can anyone recommend a very simple easy to use streaming stick that can do Jellyfin and accept Chromecast streams? I know that second half isn't self-hosted, but this is how I'm weening my family off big-streaming and big tech, one step at a time.
