Nice - it definitely isn't perfect but I am fan of Plex. I get the compulsion - my family owned a video store when I was young so I have been a collector my whole life. If I hadn't already gone thru the misery of fixing a lot of the auto-labeling errors on my existing Plex server, I would have deployed the Plex app on my NAS when I built it. I haven't been purchasing as much physical media since pre-COVID just because my local brick and mortar resource for used 4k Blurays have closed but there are some holes in my library I need to fill. If I upgrade my switch in my office to 10GB, I might spin up an instance and try to figure out how to get 4k and HDR/Dolby Vision to actually playback over Plex on my network so I only have to keep one extra tower running. It's not a latency issue, I am sure it's either a limitation of the plex app on Roku/Xbox or in the file format because it plays local from file. I just cracked the shrink on HexOS and only thing I am configured thus far was immich so I could consolidate my wife and I's photos into a single source backed up to personal cloud. If you get froggy and are a cord cutter, there are integrations for over the air TV into plex though not sure if that would be supported with a virtual instance of plex though I have no doubt someone has gotten it working. Good luck and enjoy!
