Torpedo Bombers have a set range of damage modifer from 0.8 or 1.5x times while Dive Bomber has a set 1.0x damage modifier. Unfortunately against powerful enemies, CVs don't exactly shine that much in Aerial Bombing Phase most of the time unless RNG lets you shine.

In the Event, CV's role is mostly obtaining Air Superiority for sake of your BB/CA/CLs to do Artillery Spotting and do Double Attack, Cut-In attack during Day Battle. Unless the map has low-tier CV/CVL, the CVs can't do much bombing if high air superiority is requried for the map (mostly in case of Hellcat Wo or Black Wo Shooter)

As for your bombers, I think you good but might want to get more Ryuusei Kai kinda.
