Proxmox+Immich install - How?

Hello guys, I am new to this. I want to install Immich on a PC with Proxmox. I have 1 SSD for the proxmox system, 2x HDD for storage. I will set up ZFS Mirror for the HDDs. Now, the question is should I use VM or CT. Should I passthrough the GPU? I will have other VMs on this PC, so how is this going to work? Complete newbie to proxmox here :D
