I used k3s and use the same node as master and runner. I started off with 3 nodes like you are planning, but soon discovered they for home use it just adds overhead in keeping up to date and backing up, and I had to find some way of doing persistent storage without standing up yet another VM as a NFS host, so downsized to a single node.
