“Cease and desist” has nice assonance, I feel “pursue and persist” matches a little more in that regard, though both are decent.
As regards meaning, “proceed” and “pursue” are both good, taking slightly different angles but to essentially the same purpose.
Continue - hold together (cum + tenere -- same root as contain)
Proceed - go forward (pro + cedere)
