However I also imagine that if I blocked these vents off, the would be an increase in negative pressure in the wheel wells. But smoother air flow.
Which would be the better option, to block or not to block?

Ford may have measured a constant Delta-P between the engine bay and wheelhouse at this location at all driving speeds,and chose it specifically do to this pressure relationship.
Cabin ventilation outlets are designed this way to save pumping energy of an air mover.
Without a complete pressure survey of your Taurus,you're shooting blind.
