I like the look of the mid tunnel P-Nut / wassell style tanks but notice most of the aftermarket ones have dual petcocks. Do most people plug one side or run two petcocks and lines to a T before the carb?

Depends on your desires and what fits your mosickle best.

Tiny tanks like those with the bungs toward the rear wouldn't benefit from dual fuel valves since they trap so little fuel.

Dual petcocks on some British bikes like Triumph were used as main and reserve and to get more usable fuel because of the tank design.

Dual bungs obviously give choice of both sides when mounting a single petcock which saves fabbing two different tanks and all the stock number, ordering, and returns from customers who ordered the wrong tank bullshit that would entail.
