Owner want to reuse old dishwasher. Was hardwired. I will try and Google manufacturing recommendation. But if given the choice between hardwiring and cord plug... Would it be a better install to use a wet listed, hard usuage cord?
It is fed by a gfci breaker.

If hard wiring is dictated would mc cable be an over kill instead of Romex?

Were dishwashers in the 80's even permitted to be cord and plug connected, we always hardwired them back then. Under the 2014 NEC the manufacturer's instructions would be needed to see if a cord and plug connection is permitted.

422.16(B)(2) Built-in Dishwashers and Trash Compactors. Built-in dishwashers and trash compactors shall be permitted to be cord-and-plug-connected with a flexible cord identified as suitable for the purpose in the installation instructions of the appliance manufacturer where all of the following conditions are met:
(1) The flexible cord shall be terminated with a grounding type attachment plug.
Exception: A listed dishwasher or trash compactor distinctly marked to identify it as protected by a system of
double insulation, or its equivalent, shall not be required to be terminated with a grounding-type attachment plug.
(2) The length of the cord shall be 0.9 m to 1.2 m (3 ft to 4 ft) measured from the face of the attachment plug to
the plane of the rear of the appliance.
(3) Receptacles shall be located to avoid physical damage to the flexible cord.
(4) The receptacle shall be located in the space occupied by the appliance or adjacent thereto.
(5) The receptacle shall be accessible.
