The reservation, whether on cash or points only grants club access.
So yes, you can book a standard King/Twin Room with club access (which of course could be referred to as "club access rooms"), but there is no more "Club Room" category.
In any case, it is not relevant to the OP's question. They cannot book a room on points, with or without club access, for the 2 adults + 2 children they mention.
Yes,
OsakeWino is correct, with points, you can book a base room or a base room with club access, but neither will allow for 2 adults + 2 children.
What you can do is just book the room with two adults with points, then contact the hotel to see if they will upgrade the reservation to a Deluxe room that will accommodate the entire party. I did something similar a couple years ago, and at the time was charged about 9000 yen a night for the guaranteed upgrade.
