I'll give this a go.

Above all I think the most essential tool for me is Spectacle https://www.spectacleapp.com/

Homebrew is also a requirement.

Iterm2 to replace the default terminal. I also added this https://github.com/SebastienElet/iterm2-borderless.

Everything else is pretty developer specific in my opinion. I'd recommend Visual Studio Code for a text editor (if you don't already have a preference). It has built-in git integration and installing new plugins is trivial.
