Proxmox is just Debian with a qemu and lxc webui. You can do anything with it

Agreed, I just don't see the point for a "homelab." Unlike many, I like very straightforward setups based on a regular distro like Debian. I also run many services bare metal. This includes nginx, email stack, DNS server, game servers, etc. I use use virtualization/containers for things that I treat as an appliance. This includes Home Assistance, Nextcloud, Matrix, Jellyfin, among others.
