Flap selection is done at VFE NEXT - 5KT. Which means Flap 2 at 195 kt. Gravity Gear extension then flaps.
My copy of
FCOM 3.01.20 p.3 note 1
does not have any crosswind notes - perhaps this is airline specific? I am not aware of any Airbus wet runway prohibition - and in any case if the only suitable runway is wet/contaminated you have to use it, so the information is necessary. Better to land on a wet runway than fly for an hour on only one hydraulic system.
