I mean, GDScript doesn't exist outside of the Godot engine. Debugging for it is the same as debugging a Godot game. All GDScript functions are C++ methods. Also, there are type hints if you want.

If you're going to be doing a very large, ambitious game, odds are you'll also be creating your own C++ methods and thus debugging using C++ tools and the game engine tools...
