I personally liked Plex a lot better than Jellyfin, even though it’s open-source. They worked about the same and Plex’s layout is a lot more pleasing to me and my family/friends.
After a year of local music, I don’t see the need to stream at all. I have more than enough space on my phone and no worries when driving through places with bad Internet. Plus I don’t miss anything when I enable Airplane Mode.
Ahh yes, very interesting.
