The menu-search feature did exist in Unity on Ubuntu at one point but it was not as nice as the macOS one. I think it's a hugely underrated feature in macOS. Another related feature that I wish some Linux gui framework would adopt is the concept of global keybindings. Every menu in every app in macOS displays by default the shortcut key next to it - if one exists. These are the kinds of features that are easy to overlook but contribute hugely to the "cohesive" feeling that macOS advocates so often seem to have trouble describing to Linux desktop users.
