for your use case, you could just stick to a 2tb nvme, optionally with a usb adapter to make it easy to share movies with people, and just swap it out when you run out.
I already know there are issues with this approach (you want plex or you want a single drive for everything), but personally I don't really spend any time rewatching anything.
The only reason you are getting 10tb is because HDD's only start being attractive at 10tb, but it's really not necessary depending on how many gigs you download per day. If you downloaded 1 gig per day, 2tb is going to last you years.
(and plus, I like copying movies onto people's PC's, it's not ideal but some people just have a terrabyte of free space and I have a relatively small collection of movies since I don't like blueray rips)
