As long as the all the planes in a slot are not shot down, slot size does not affect CV damage during the shelling phase. The shelling damage increases based on the stats of the planes equiped. The top Torpedo bombers and Dive bombers offer approximately the same bonus to shelling damage.

Formula for CV/L shelling damage: (Firepower + Torpedo) × 1.5 + Dive Bomber Stat × 2 + 55

The slot size does increase the damage for the preemptive airstrike.
