As commented above, there’s nothing truly special about this menu.
Each “card” is a separate widget. Overlay/Canvas + Vertical Box for the text blocks, and a 9-slice (maybe even without) border for the highlight.
The whole thing seems to be sitting in a Widget Switcher - the tabbed layout.
The layout in the last reference can be done with a grid panel where you decide how many rows / columns a “card” would occupy. But it can be laid out manually in a canvas if there’s just 3 of them for the sake of simplicity.
The darkened edges are, most likely, incorporated into the image itself; but this effect can be achieved in the material that sits on top - in case this needs to be animated / dynamic.
