A There are pros and cons to floor receptacles. The benefit to having floor plugs in large rooms is that there will not be long cords stretched out across the floor. The down side is that you must know exactly what furniture you will use and where it will go. I have seen it time and time again that once the house is complete the electrical outlets in the floor don’t end up hidden under the furniture like planned. Just make sure that if you choose to use floor plugs you like the looks of them. Or, be okay with your furniture placement being dictated by the plugs.
