With macOS’s setup, I can command-tab to any open app (e.g. preview), hit the up arrow and then use the arrow keys to quickly open a recent document. Without the app model macOS uses, this is a lot less convenient, and I miss it every time I use my KDE Plasma Desktop.

If you use the cascading Application Menu widget, Win -- Arrow Down -- Arrow Right gets you to the recent files menu.
