Just went to WDW's site. Unless I miss my guess, "standard" concierge means just that, standard rooms on the concierge floor, as opposed to any of the concierge suites. You would get all the available concierge amenities, but you're in a room and not a suite.
Either that, or they could be rooms anywhere in the Lodge (as opposed to the concierge floors), but you would still have access to the concierge services. Not ever having been to the concierge floor, I don't know if it is seemingly open to the public, or if it's in an enclosed room you need your key to open. If it's the latter, I'd guess, no matter where your room actually is, your key would be able to open the concierge floor.
