Jellyfin is the way. Costs nothing other than the hardware needed and nobody is selling anything about you.
Our personal streaming library with Jellyfin is bigger than any public service and we can add to it from VHS, DVD, Blueray, though extra equipment was required for the VHS/Blueray.
It’s also available anywhere we go and we can set up separate accounts for different family members. There’s even a phone app.
We have over 15,000 videos in TV episodes, alone. Not counting movies.
So…yeah.
