Goto plugins?

[Verme]

Hi folks, been a Plex guy for a while, but I also have Jellyfin running in parallel incase anything happens/wanna test it out. Being fairly new, I'm wondering about the plugin system, everything else I think I have configured and working properly (maybe iptv will be another post). I was wondering if there is any goto's/standard plugins which everyone installs right away without even thinking about it? Maybe like if you have unraid, you install the community apps etc. I'm not sure what would be missing, but I figure I'd ask.. like is there another repository everyone uses cause it's awesome? Do you 'need' to install any plugins for quality of life purposes? Thanks in advance.

ps - If I missed a post with good info about this in it, sorry, checked but didn't see.
