Inspired by the iconic menus from Atlus' games, Godot Developer Flynsarmy attempted to create his own version, and while he admits he's very much a coder and not a designer, the result is a nice prototype. This menu, where focusing on an item affects the character's action, was built in Godot 4.6 dev2 and is available for download.
