Wish is for recovery and can be used to heal your team. Protect is to gain HP back from Leftovers and to protect yourself while waiting for your Wish support. Moonblast is STAB and is there mainly to take care of Dragon types since Florges is immune to Dragon type moves since it is a Fairy type. Finally Aromatherapy is to heal yourself and your team mates of any Status Problems.
There are alternative moves I could of given Florges such as Psychic to take care of Poison types or Toxic to badly poison opponents. But I was unable to fit Psychic into my move set. The reason I decided not to use Toxic however is because your two weaknesses are Poison and Steel types both of which are immune to Toxic so your opponent can simply anticipate your move and switch in to a Poison or Steel type to resist it.
