Is TrueNAS VM useful in my use case?

BLUF: Do I really need to run TrueNAS VM?

Newbie, running ProxMox to host Plex and associated *arr servers, Nextcloud, DNS, and about a dozen other services. I am running TrueNAS Core in VM.

I have three zfspools; one for OS install, one for Cloud storage, and one for Media storage.

In configuring my Media storage pool, I passed the disks from ProxMox to TrueNAS VM and created a SMB share. Then, apparently to mount the share to Plex, I needed to pass the pool from TrueNAS back to ProxMox. This seems overcomplicated to me but I'm not sure if my thinking is correct.

Basically I'd like some sort of management GUI for storage, just to the extent that shows me how full the storage is, errors, and if a disk goes bad.

If I do get rid of TrueNAS, how do I properly mount the disks back into ProxMox without losing the TBs of data I have on my Media storage pool?

I doubt this part.
I think as soon as the NAS is working, the others (including prox) should use it, and no additional complications.
- It's probable that I'm missing something but I couldn't get the share to be available to any other VM or LXC on ProxMox until I passed the pool from TrueNAS back to ProxMox.
  I'm all for getting rid of the TrueNAS VM as long as I can reassemble the zfspool in ProxMox without losing the data (though if I did, no big deal). And I'd also like a user friendly way of monitoring the health of my disks.
  
  reassemble the zfspool
  zfs itself can do that. The zpool members know the pool and the other members.
  
  So I don't need to take care to re-mount them in the right configuration? I'll do some googling but I wasn't sure if I needed to do some backup preparation of something.
