Plex (originally) and Jellyfin are a centralized way of managing your media with aesthetic and easy to use interfaces. I have one Jellyfin server and I have a Netflix/Display+ type interaction with my media. I have the same content on my phone, wife’s phone, my desktop, laptop, my TV, etc.

All watch history, recommendations, up next queue, and so on.

And with the right setup (Wireguard in my case) I can access that content from anywhere.
