The LabelControl AutoHotkey script can overlay buttons, controls, and other interface elements with a number. You can access the interface controls at any time by inputting the number that belongs to one of them.
E.g. here is a GIF of the LabelControl AutoHotkey script with its numbers:

I haven’t tried it though.
You can try using Hunt and Peck.
Fluent Search has a Screen Search feature that works with any application. You can just set a key-binding to invoke it and use it.
