Some feedback on this; When I make my UI, I try to design for as many platforms as possible with the least amount of differing UI. A good example of this is how websites scale certain UI elements to fit within the window/screen size. This helps scaling down on the amount of coding you might have todo.
For controller/console UI, I would recommend looking at console (XBox and Playstation) UI designs and getting a rough idea on what you might want to incorporate into your designs!
I’d also highly recommend looking into UI Frameworks such as React-Lua and Fusion.
Goodluck and happy designing!
