Verdict
Traefik is the right choice inside Kubernetes — it has native IngressClass support, CRD-based routing, and deep integration with K8s service discovery. Caddy excels as an edge proxy or reverse proxy outside of Kubernetes, with an elegant Caddyfile config and excellent HTTP/3 support. For a Hetzner cluster, use Traefik as the in-cluster ingress controller and optionally put Caddy on a bastion/edge node for non-Kubernetes traffic.
