The ultimate setup is actually running esxi directly on the mac mini 2018 (6c/12t) and 64G DDR. Then esxi can launch as many macos, windows, linux and nested esxi vms as needed. 4 tb3 allows plenty of options for extra nvme or 10+ GbE nics. You can even passthrough the intel iGPU to linux and light up a monitor.
Compare to a modern mac mini has a strict limit of 2 macos vms, no hyperthreading , no nested virt and CPU optimized for vertical integration.
