Some services run really good behind a reverse proxy on 443, but some others can really become an hassle… And sometimes just opening other ports would be easier than to try configuring everything to work through 443.
An example that comes to my mind is SSH, yeah you can use SSLH to forward requests coming from 443 to 22, but it’s so much easier to just leave 22 open…
Now, for SSH, if you have certificate authentication or a strong password, I think you can feel quite safe, but what about other random ports? What risks I’m exposing my server to if I open some of them when needed for a service? Is the effort of trying to pass everything through 443/80 worth it?

If you are trying to access several different services through the internet to your home network, you are better off setting up a home VPN than trying to manage multiple public facing services. The more you publish directly to the public, the more difficult it is to keep up with everything; It is likely needlessly expanding your threat exposure. Plus you never know when a new exploit gets published against any of the services you have available.
