As mostly a Windows user, I like the macOS approach. Applications go to /Applications/, application data go to ~/Library/Application Support, settings go to ~/Library/Preferences. Installing an application is mostly done by drag and dropping to Application directory. To delete an app, just delete it from Applications directory.
