I run a similar number of services on a very different setup. Administratively, it’s not idempotent but Proxmox is a delight to work with. I have 4 nodes, with a 14900K CPU with 24 cores being the workhorse. It runs a Windows server with RDP terminal (so multiple users can get access windows through RDP and literally any device), Jellyfin, several Linux VMs, a pi-hole cluster (3 replicas), just to name a few services. I have vGPU passthrough working (granted, this bit is a little clunky).

It is not as fancy/reliable/reproducible as k3s, but with a bunch of manual backups and a ZFS (or BTRFS) storage cluster (managed by a virtualized TrueNAS instance), you can get away with it. Anytime a disk fails, just replace and resilver it and you’re good. You could configure certain VMs for HA (high availability) where they will be replicated to other nodes that can take over in the event of a failure.

Also I’ve got tailscale and pi-hole running as LXC containers. Tailscale makes the entire setup accessible remotely.

It’s a different paradigm that also just works once it’s setup properly.
