The settings that mainly affects the results are the Shape
Ridged Body Tag>> Attribute Manager> Collision> Shape> Moving Mesh, as well as the Offset of the clones,
Voronoi Fracture>> Attribute Manager> Object> Offset Fragments.
The Offset value was chosen during the caching, to have no intersecting clones. After the caching the value was set back to zero
The values for Bounce, Friction as well as the dampening parameters (Force) of the Rigid Body Tag might vary from case to case. The dampening pulls the energy faster out of the chunks, to avoid vibrating in the final phase.
In some cases, it is supportive for the Solve to have an eye on the Project settings - Dynamics> Expert.
As a side note, there is always the option to help with a collider object to kick things, the collider object can be invisible.
All the best
