You have Akashi? If that is true then focus on the following list:

All 20.3cm (No.3) >>> +6

4x 20.3cm (No.2) >>> +4

2 x 35.6cm >>> +4~(Max) [Do not upgrade to Prototype 35.6cm] OR 2 x 38cm >>> +9 [Since you have Bismarck]

4~6 x 41cm >>> +2~4 [Only improve when you have more than enough 41cm to spare, also try to rotate and improve each 41cm required one at a time.]

All 61cm Quint Torpedo >>> +6 [Consumes 3 screws, might sting a little. Eventually, you will need 7~8 of these.]

All Type 91 AP >>> +6 [Cheapest improvement and can be easily done from daily quest.]

Searchlight >>> +6 [Whatever you do, do not upgrade it into Type 96 150cm Searchlight.]
