Put my vote on the M520 list. They offer everything you say you want.
Just for clarity:
M520: 2 sided SPD pedal
A520: Single sided SPD with a platform around the mechanism
A530: SPD on one side, platform on the other.
The difference between the A520 and the A530 is that the platform on the A530 is meant for regular shoes and is on the opposite side of the pedal from the mechanism. One side is for clipless, the other is for regular shoes. The A520 is not intended to be used with regular shoes.
