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.

Do two NICs. I have a bigger setup, and it's all running on one LAN, and it is starting to run into problems. Changing to a two network setup from the outset probably would have saved me a lot of grief.

So dual NIC on each device and set up another lan on my router? Sorry it seems like a dumb question but just want to make sure.

Why would you need two nics unless you’re planning on having a proxmox Vm being your router?

Security. Keeping publicly accessible and locally accessible on different networks.

Hmmm - not really any more. I have everything on the same VLAN, with publicly accessible services sitting behind nginx reverse proxy (using Authelia and 2FA).

The real separation I have is the separate physical interface I use for WAN connectivity to my virtualised firewall/router - OPNsense. But I could also easily achieve that with VLANs on my switch, if I only had a single interface.

The days of physical DMZs are almost gone - virtualisation has mostly superseded them. Not saying they're not still a good idea, just less of an explicit requirement nowadays.
