macOS has tons of power user features built in. Automator, Service Menu, Shortcuts, Folder Actions, intelligent folders, and much more! Adding commands to the contextmenu, that then work across apps is super cool and easy to do for example.
In any app, I can select text and then use the service menu or context menu to run my own text transformation scripts (title case, replace, etc.). Only using built-in tools!
Also you can add or change keyboard shortcuts for every app, even if it doesn’t have them for some menu items. Do you want to not accidentally quit Firefox with cmd + q ? Change it to cmd + alt + q in System Settings.
How many windows do you have open?
