The primary reason to virtualize is to maximize the “bang for your buck” on your hardware. Containers are great, but have their limits.
So long as you have a desire to learn it (and the budget), I say dive in with Proxmox and see how you can put that hardware to use. VMWare ESXi is more common in a business/enterprise setting, but costs money to for anything beyond the basic functionality after the evaluation period.
I was excited for the Roborock map. Unfortunately it isn’t live and doesn’t appear to be interactive. A good step in the right direction, though!
