Fighter Bombers are used when you need some extra AS value while using Fighters. An example would be using 4 BB 2 CVL for the 1st fleet in combined fleet and you can gain the required AS with either 3 Fighter + 1 Fighter Bomber or outright 4 Fighters per each CVL.

Some players prefer at least having 1 Bomber + 3 Fighter just so the CVL can attack while some just outright use 4 Fighters because in Events a bomber in a single slot (even if it is located on the highest numbered plane slot) can still die quite fast and barely do much.

Personally because Fighter Bombers are quite weak in damage, I like to use them on my CV(L) when I use them as escorts for Power Leveling my CA/BBs in World 3-2A or 5-4.

In Events if you are against a boss with very high armor (Ex. Abyssal Twins Princess), use of Torpedo Cut-in is recommended to give a good high damage output (majorly by DDs with 30~35+ high luck). Double Attack is mostly used by ships who can reach the damage cap output such as CLTs, or high firepower/torpedo CAs (Ex. Choukai Kai Ni)

So generally speaking you only need Double Attack if the enemy doesn't really have high armor stats, while Torpedo Cut-in is recommended if the enemy has high armor and your DD/CL cannot give a good damage output with Double Attack alone.

In case you are using FBBs in 2nd fleet for Combined Fleet however, due to how damage calculation in night battle works, FBBs excluding Bismarck Drei tends to have lower damage output against such high armored bosses generally, hence why players prefer using CA(V)/CLT instead of FBB in 2nd fleet (In case you are facing against an Installation-type however, Damage calculation is done differently so then the entire fleet & equipment setup should be different)
