right now it's chrome, vscode, python, intellij, homebrew, and whatever C/C++ toolchain is on the system so for me rn is Xcode. I warn that my must-have change very often, I can't stand digital clutter and I often factory reset my machines and change devices often (this week I been mostly on my mac mini but the past month I was on an ubuntu machine and a chromebook) so if it takes too long to setup I don't bother with again.
