Any, really. All if you completely loathe yourself, though:)

Honestly, jellyfin is the way to go, though. At least it's just you hating yourself and not a whole company and ad machine hating you too, like with plex.

Either works. Plex is heavy down the enshitification path but is great for remote access sharing. And Jellyfin is harder to get hardware transcoding going well and the clients aren't as good and it's very insecure to run for remote access (basically you need to VPN into your home network instead of public remote access).

edit: fixed "so secure" to "insecure"

Yes

Plex

Jellyfin. Absolute dumpster fire with any remote. I honestly can't believe they have made a remote friendly UI.
