Looks more like Max10 sized. It looks like there is a small door behind the wing, which matches the location of the back end of the cabin. There’s no window in them, but they are probably depicting the aft emergency exits, given regulatory requirements that exits be on both ends of the cabin. Based on the cut away, I think the large door aft of the main door, that has no window is likely the cargo hold door. It doesn’t look like there’s a hold under the cabin. The main door appears to be extra wide, which improves the exit capacity of the door, and reduces the actual number of exits required. There’s also the option for a ventral exit, but those are pretty rare on passenger airliners.
