Background

Hello fellow self-hosters and homelabbers, A few weeks ago I was able to fill my new NAS with the proper hardware I needed to expand on my earlier setup.
Due to the new capabilities I also wanted a fresh restart. But the more I think about doing one thing, the more I hit other road blocks amd think about doing Y.
So I wanted to ask how you would solve my goal.

My current (main) setup:

Hardware: 11th Gen i5 Nuc with a 8TB HDD attached via USB
OS: Debian 11
Software: OMV6 for management and Docker for a diverse set of containers
Current containers: HortusFox + MongoDB, *arrs-stack, Jellyfin, uptime kuma, unifi network application + mariaDB, traefik, wallos

Current available hardware for use:

1x 13th gen i3 NUC running Proxmox 8.2
1x 11th gen i5 NUC
1x uGreen DXP4800+ NAS with 4x15TB HDDs in Raidz2. The OS is TrueNAS scale

My plans:

NAS storage made accessible via NFS to the proxmox VE.
NAS storage mainly planned as mass-storage for Jellyfin.
Reimage my 11th gen NUC with a bare-metal Debian install for Docker.
(I will not virtualize on the 11th Gen NUC because I can’t pass the iGPU to the VM and not really interested in LXC containers)

Problems and questions I have at this moment:

1: Should I do a media-storage VM only utilized for serving media and do the computing on another VM or do a general VM for both?

Upside to an all-in-one VM: Less problems with serving storage between many different nodes and keeping it organized.
Upside to specialized VMs (storage & compute VM): Better focus on ressources like CPU and RAM.
2: Should I place my whole docker stack again on the 11th Gen NUC or place the stacks in their own VM(s)? Example:
service stack in service-focused VM
media-focused stack in media VM (which also serves the files for jellyfin)
Jellyfin bare-metal/dockerized on NUC 11th Gen

I hope someone can maybe help me untangle my grown mess and plans. My skills with Linux are not very deep and very beginner level. If you are willing to help please be patient with stupid questions.

If you have any better solutions, pointers to research, (blog) articles on architecting such solutions, examples how you solved storage/management or just willing to help me, I’d be very grateful :)
