Opening ports essentially allows other computers on the internet to initiate a connection with yours.

It’s only dangerous if a service running on those ports can be exploited.

“If” is not the correct word choice. It’s only dangerous when a service on the port gets exploited.

  Driving a car is only dangerous when you die in a traffic accident.
  
  your logic doesn't check out.

    If it’s exposed to the internet it’s a matter of when, not if, it is compromised.

to reduce attack-surface, if there’s no reason for the port to be open, don’t open it.

This, coupled with the fact that firewalls are protocol-agnostic. You can, for instance, use ‘port https’ in your Packet Filter config instead of ‘port 443’, but that simply means that PF will block/pass traffic to whatever service is bound to that particular port, and NOT https connections in general.
