There is no concrete evidence of ship's luck affecting development or construction. Currently, it is only a placebo at best. Only real use of luck is night battle cut-ins: Luck increases the chance of activating night battle cut-in attack, of which in particular a torpedo cut-in attack can be extremely powerful on the likes of DD, CL, CLT, CA(V) and SS. Due to that, the usual targets for luck modernization are DD, CL, and CLT, sometimes a CA(V) or SS.

BB are unable to use night battle cut-ins with good efficiency - they are just simply not flexible enough to use them to their full potential and main gun night cut-in attacks are not considered as effective. As for CV(L), as they are unable to participicate in night battle, luck is an useless stat on them.

CA(V) and SS, while they can make use of night cut-in attacks and SS pretty much always use them anyway, they are not common targets for luck modernization - for SS, it is because of their limited combat potential and for CA(V), there are not many of them with high natural luck stat. Luck modernization is in general a very long process, and you'd want to avoid raising the luck of a ship who's natural base luck is very low. CA(V) in general utilize night double attacks well enough anyway.
