Agreed, though I combine using Little Snitch with Radio Silence: https://radiosilenceapp.com Little Snitch is great for when I want hyper granular control of a specific app's network permissions while Radio Silence gives me a super quick way to just block EVERYTHING for a particular app right away without even opening it the first time. - Source: Hacker News / 11 months ago

Forgot to mention Radio Silence (commercial), seen by many as an easier introduction vs Little Snitch. Source: over 1 year ago
Sorry for the late reply. I use Lulu which should be enough, but I also simultaneously use Radio Silence to be safe. Source: almost 2 years ago
Little Snitch (LS) is considered by many to be the gold standard. The aforementioned Lulu has a good reputation. The app Hands Off! Appears to be no longer developed (site offline). Then there's Radio Silence that may well fit your needs. Finally, one or more apps by Murus may be of interest but AFAIK these are not easy to configure and may be overkill for the average Mac user. I'm not familiar with TripMode. Source: about 2 years ago
Polymail - This one is a lot like Twobird but with a lot more features. It's a different type of email client. It's really cool, but the Windows version is just a web app. It's available on iOS as well. Source: over 2 years ago
