Jellyfin
I have heard people suggest Jellyfin and plex a lot in the self hosting communities. Also I just realized it took me 4 days to reply the the comments after I posted. Well better late than never.
Desktop: Freetube. iDevices: Yattee. Android Devices: I'm not sure yet.
Why not Freetube on android?
I have been unsuccessful trying to root my android device. The best I could do was disable some google services and use fossdroid. I may add freetube to the list as well.
Probably will at some point, yeah.
Newpipe
I have heard Newpipe is good.
It is. Simple too
