Well, this was disappointing, as the question from the title was not answered. It was left as, "we don't know".

Results from Imperial College of London impact calculator:
Calculated Results (ic.ac.uk)

9 km diameter crater
0.6 km deep
Complete destruction out to about 100 km.

Does this take into account the "pile of rubble" nature of Ryugu, as opposed to a more solid piece of rock?

Yes, this simulation has it breaking up 77 km high in the atmosphere. Only small pieces reach the ground, but there are a lot of them. They hit a footprint 1.2 km x 1.8 km.
