Planning on setting up Proxmox and moving most services there. Some questions (midwest.social)

I am currently running most of my stuff from an unraid box using spare parts I have. It seems like I am hitting my limit on it and just want to turn it into a NAS. Micro PCs/USFF are what I am planning on moving stuff to (probably a cluster of 2 for now but might expand later.). Just a few quick questions:

Running arr services on a proxmox cluster to download to a device on the same network. I don't think there would be any problems but wanted to see what changes need to be done.
Which micro PCs are you running? I am leaving towards HP prodesk or Lenovo 7xx/9xx series around 200 each. I don't really plan on getting more than 2-3 and don't run too many things, but would want enough overhead if I switch stuff over to home assistant and windows and Linux VMs if needed.
Any best practices you recommend when starting a Proxmox cluster? I've learned over time it's best to set it up correctly than try to fix stuff when it's running. I wish I could coach myself from 7 years ago now. Would of saved a lot of headaches lol.

I want to like XCP-ng. Unfortunately my primary use case is VMs or containers working with attached USB devices. On Xen it seems like an absolute nightmare to passthrough USB or PCI devices other than GPUs (as vGPUs).

Even on Proxmox it has been frustratingly manual.

I'm planning to try out k8s generic device plugins. I don't really need VMs if containers will cooperate with the host's USB. I'm sure that will be a bit of a nightmare on its own and I will be right back to Proxmox.

I hope someone will tell me I am wrong and USB can be easy with Xen. I do prefer XCP-ng over Proxmox in many other ways.

Here's their documentation. The tip suggests it may have been harder in the past but it doesn't seem too bad now. Hopefully this is configurable in Xen Orchestra in the future.
