Firewall everything you can on as many connected devices as possible, at least their ingres.

I personally consider "desktop firewalls" (...) unnecessary.

BUT: It depends a lot on the nature of your network. ...

As always when talking about security: Almost everything depends on your scenario

Yes, it cannot be repeated enough: It depends on personal/local scenarios and needs.

Let me just add one aspect: If you have just one firewall at the gate/router this is a single point of failure scenario. I have seen failures that were not noticed for a long time because nothing got blocked.
