Which inversion should you use?

Whichever one your hand is already near. Inversions exist so consecutive chords can share keys — instead of jumping the whole hand to a new root position, you move a finger or two and the chords melt into each other. That is most of what separates piano playing that sounds smooth from piano playing that sounds like a series of separate grabs.
