What you're looking at is a wall box that has an outlet cover and is plastered over. Your standard outlet has an oversize faceplate on it. You can buy a regular size faceplate that will be the same size as the port cover. You can also buy an extender for the thicker wall.
The other style outlet you're thinking of is called a "decora" and is rectangular. The light is usually on a gfci outlet version or USB version.
