Glasswire and Tinywall(?) are like this.
Simplewall works great, it's open source. And yes, there are a couple of million requests made by windows apps alone, which are completely fine to block. Simplewall also blocks windows telemetry. I have to use win11 at work and it's an absolute ahitstorm of network requests that you don't get to see when using windows firewall.
Glaswire looks beautiful and functions well, but you will hit the paywall after a couple of weeks (I used this on the around 2010 I think)
Right, Simplewall, not Tinywall.
