It really depends on the food. Bananas stay out but strawberries, apples, lettuce and tomatos stay in the fridge. Different foods are different for us.
Generally follow how you would find them in the store. Lettuce, carrots, peppers, grapes go in the fridge. Everything else sits out. I keep bananas separate from my fruit bowl because they will make other fruits ripen faster and I throw them in the fridge once they have reached the ripeness I like.
