How hard is replication across servers with just debian and qemu? I’m honestly not super great on linux knowledge. I’m a Windows sysadmin by trade, with maybe 10-20% linux. I run a few Ubuntu server VMs at home and some RHEL at work. So I’m looking for something as easy to set up and well-documented and supported as possible. Proxmox just seemed like the “industry standard” for selfhosting, but I was also looking at Unraid (which is supposedly better at storage and less good at virtualization) or even ESXI, but I didn’t want to get into the VMWare payment bubble if I needed anything more than a simple host.

I hadn’t seen that. Thanks for the link! That’s definitely gonna be helpful.
