To be fair: Most of them are documented in Apples manual. If you open the macOS help on "Manage app windows" you will find all the tricks about moving and resizing discussed here. Or your WiFi trick is mentioned in the help article about debugging your WiFi connection.

The builtin help and documentation on macOS is surprisingly good. Especially if you compare it to Windows. Today was the first day I looked at it. The last 10 years on Windows taught me that the help outside of technet and Office is useless and I assumed this is also true for macOS. I guess I was wrong and I should have read the manual.
