It may not be a light carrier, but the concordia class shares a similar hull design to the Victory. The WC4 carrier nav map kind-of hints at some of the room placement on the lexington and obviously flight control is right beside the flight deck...
As for WC3 you can kind of imagine all the rooms placed around a central elevator. However there really isn't any official schematics .
There are some drawings of the movie Tiger claw in the Confed Handbook. and there was a neat cuttaway poster that was made but was never released and has since disapeared.
