Hypervisor: Debian stable + libvirt or PVE if you need clustering/HA VMs: Debian stable podman if you need containerization below that

You can migrate VMs live between hosts (it’s a bit more work if you pick libvirt, but the overhead/features or proxmox are sometimes overkill, libvirt is a bit more barebones, each has its uses), have a cluster-wide L2 network, use a machine as backup storage for others… use VM snapshots for rollback, etc. Regardless of containerization/orchestration below that, a full hypervisor is still nice to have.

I deploy my services directly to the VM or as podman containers in said VMs. I use ansible for all automation/provisioning (though there are still a few basic provisioning/management to bootstrap new VMs, if it works it works)
