I would improve BB guns, AP shells and 20.3cm (no.2 & no.3). The reason for improving BB and CA guns is that it is much more important for BB and CA to hit compared to CL and DD (accuracy bonus from improved guns and AP shells is sqrt(4*n), where n is the number of improvements made). Surface radars like the type 22 surface radar kai yon and the type 32 surface radar are also good choices to improve.

It's also more beneficial to spread out your improvements due to diminishing returns. A good threshold is +1 (additional +2 accuracy, +1 firepower) and +4 (additional +4 accuracy, +2 firepower).

Equipment I would hold off improving are torpedoes as they do not get an accuracy bonus, and type 94 AAFD -> 10cm HA + AAFD as AACI is mediocre for ships not named Maya and Akizuki (and maybe Isuzu).
