There is a set of 10,000 CVRP instances with 100 jobs each available on CVRPLIB. They are modeled on the X generation pattern and were primarily designed as a framework for evaluating ML approaches as all optimal solutions are known, see this paper for the rationale.

It would be interesting to test on those.
