Having operated into CDG numerous times, when there on easterlies what tend to do is for landing traffic to land to land on 09L or 08R (the outer runways) and departing traffic to take off from 09R or 08L (the inner runways) and likewise when they are on westerlies - Landing traffic lands on the outer runways and departing traffic take's off from the inner runways. The only exception to this is when they are doing maint or resurfacing on one of the runways.
