It would be nice to know whether the firewall is blocking anything, but it offers no stats for this.

If you are running a NATing router (which pretty much all consumer grade routers are) then it is not 'blocking' anything ... what it is doing, or actually not doing, is allowing anything from the outside in.

What it is doing is simply allowing computers on your private network to access the internet.

Anything from the outside that tries to get in will simply hit it's head against the wall.

This is perhaps one of the reasons I consider for
using a software-based firewall, so that I can see what's hitting my PC.

Who really cares what's hitting your system ... So long as all it's hitting is your router, you are safe.

The other is that, as good as a hardware firewall can possibly be, it isn't
infallible.

Routers and software firewalls are totally different animals ... a software firewall's job is to stop external systems from being able to access your PC. This is very important to have whenever you are dialed up to the internet or if you have your PC directly connected to your broadband connection.

When you are using a NATing router, then nothing can get to your PC because your PC isn't on the internet directly. The only thing that's actually on the internet is your router and it doesn't offer any services that can be exploited.
