Single master k3s with many nodes, one vm per physical machine. A couple of downsides to note: you are limited to flannel cni (no network policy support), single master node by default (etcd setup is absent but can be made possible), traefik installed by default (personally I am old-fashioned and I prefer nginx), and finally upgrading it can be quite disruptive. Therefore, the issue has to be in the only difference between those deployments: k3s vs k8s hard disagree, k8s on bare metal has improved so much with distros (k3s, rke2, talos, etc) but Swarm still has major missing features - pod autoscaling, storage support (no CSI), native RBAC.
