I’ve had luck exploring the upstream’s source repositories. Often, ‘official’ charts are in the repos, but not pushed anywhere. Also, if you aren’t averse to Bitnami, they’ve quite a large collection of charts and applications which receive care and maintenance.

In the places where I’ve had to make similar decisions, I’ve used the need for ‘advanced’ features to make the call. If I’m looking for storage or networking redundancy, or I’ve been interested in running multiple hosts systems, or I’ve been looking to play with overlay networks, then I’ll grab Ovirt, Proxmox, VSphere, or Openstack (depending). When I just want something simple-ish, I just KVM / Podman on a Linux machine.
