Not sure if I am missing something, since a simple Google search or asking r/selfhosted would have been more appropriate IMHO.

To awnser your question. I have only used docker registry (core) since I like stuff in modules and it works very well. It comes in a docker image. To setup it needs like 2 minutes. It can be secured with credentials which I highly recommend. My registry is also running behind treafik, which provides it with a valid ssl certificate and running directly on port 443, which looks nice and professional.
