Look at K3s. Since a while it has built-in support for Tailscale (can also use Headscale).
Alternatively, it doesn't really matter how or where your nodes are located, if you add a VPN to allow them to talk to each other.
Your main issue would be storage. But that's easily fixed with a topology aware CSI and then keeping your stateful workloads either wherever they got their volumes provisioned, or forcing them to be provisioned on your home servers.
That is what rook-ceph or longhorn is for. Longhorn is good for beginners
Good point about Tailscale. It hadn't occurred to me.
How does DNS work for a Tailscale-networked cluster of servers?
My understanding is at least one of the nodes would need to be designated as the ingress. I could potentially also have all the master nodes hold the ingress, but then I believe that means I'd need to use round robin DNS in cloudflare to ensure the domains are always pointing at the cluster.
Storage might be a problem, but being more cloud aware potentially means I can run DuckDB against minio to scan S3 objects when doing data-intensive tasks.
