After quite a few hundred crosswind landings it doesn't get any easier if the wind is gusty...
I was taught to make a "firm" (read not "hard") landing if in gusty crosswinds with less or no flaps selected. However I was taught at a nice airport with a long asphalt runway.
However you state you are practicing soft field landings... in this case I would still try to make it a bit softer than you would otherwise on an asphalt / concrete runway as its supposed to be a "soft" field landing after all - you wouldn't want to slam an aeroplane down on wet grass do you?
Are you using Mooney's for the Commercial? If its the University and Daytona my isntructor did hers there and said they used Mooneys which are even heavier in the flare than the Arrow IV... if so good luck! ;-)))
This probably doesn't help much but its my 2p worth.
Best wishes,
