I have a Synology DS923+ as my NAS which currently runs Plex, Immich and a couple other things.

I also have a Intel NUC (8th gen) which has Proxmox on it which mainly does PiHole and HomePage. I would like to use the NUC for PiHole, Immich, Plex, HomePage and Home Assistant.

Is Proxmox the best system to use for these applications? Would it be easier to just install Debian and Docker and run everything through containers on one OS instead of splitting them all up into LXC or VMs?

I would also like the convenience of easily updating containers through a GUI. I am not afraid of SSH and CLI but it's nice to go to a browser address and see everything in one place. Kind of like how DSM7 is set up on Synology.
