In 1943 the Italian bomb wing was practically reduced to Torpedo bombers.
In 1943 Italians had the 5 serie of Fighters: Fiat G.55, Reggiane Re2005 and Macchi 205(V with Macchi 202 wings or the version N with longer wings for better high altitude) Macchi was more common and the Fiat was the overall better with upgrade capability that the Germans considered it for Luftwaffe. Reggiane was the faster one could get more than 900km/h in a dive but was fragile for what it could do. So i would say Macchi 205 and Fiat G.55.
For evolution of G.55, G.55S with torpedo and G.56
http://en.wikipedia.org/wiki/Fiat_G.55#Fiat_G.56
Re.2001 is the fighter and attack carrier plane. It could have a 630kg armor piercing bomb in attack or the Silurotto-small torpedo.
And Ro.43 was the old shipborne floatplane. Italy didn't recover the flotplanes, they went back to the naval base or anchorage.
The Italians battleships in 1943 had the Re2000 as emergency fighter due to lack of carrier it had no floats and went to a land base.
Fighter Bomber Re 2002, other older options ex.fighters: Cr.42, G.50 and Mc.200.
Bombers i would say the Cant Z.1018, Cant Z.1007 ter(III), Piaggio 108 - and the Piaggio 108 with 102mm gun would be good chrome plus the good old S.79 ter(III) that still was in combat in 1944.
Patrol Floatplanes the Rs.14 and Z.506 but i would say that italians by 1943 already prefered to use bombers for offensive patrols. Floatplanes only for coastal work and anti submarine. Also for anti submarine Caproni Ca.314 and Fiat.Br.20 a former bomber.
Transport: Sm.82, New in 1943: Piaggio 108 transport version and

Notable Weapons: Silurotto - small torpedo for fighter bombers

Fighter like G.55 also could take a torpedo even a big one.
There is also the Italian circular torpedo Motobomba in both airforces, called LT350 in Luftwaffe:

There are many concepts-prototypes not operational:

A cheap wooden fighter said to be ordered into production that didn't happened by Germans and Japanese:

If you want chrome for long range and probably impossible to work in game

A final note for Germans if naval combat is expected the Do.217K with Hs293 missile and Fritz-X guided bomb would be there.
