I'm genuinely confused about how motion works for shape casting here. The cast_motion doesn't return collision information so is it expected to do a cast motion to find how far the object can go until collision and then do another collision query at that position to get the info?
Essentially two collision checks? Or is the first query cached and if then called through get_rest_info it only returns a dictionary value?
There's been so many discussions about this outside that I'm sorry but I'm asking here now for clarity :-).

Note that shape-casting with get_rest_info returns the collision normal in the returned normal dictionary entry, unlike ray-casting with intersect_ray that returns the surface normal of the hit face there.
So if you require the surface normal from a shape-cast, you can do an affirming ray-cast near the reported collision point and collision normal, though I wonder if Godot could forward this information to the dictionary in the future.
