Overload penalty is pretty negligible outside combined fleet, but you want to avoid it as much as possible in combined fleet maps. Don't go beyond the 38cm guns on Kongou-class if possible (not too sure about the pasta cannons but they feel pretty similar to the 38cm in terms of accuracy so far).

Firepower modifier from Sanshiki is applied pre-cap, so the effect isn't that prominent in day battle; assuming you have 146 firepower and at least parallel engagement, you're only going to get around 15 extra firepower, which is noticeable but nothing extraordinary. And then there's the ammo penalty and random armor modifier as well (with that much armor, nearly 100 damage of difference depending on the random number you roll).

AP shell shines at night though; if you don't see a difference you're either missing a lot or you're using the Type 3 shell on a ship in the main fleet instead of escort fleet. Night battle equipment + Type 3 shell in escort fleet helps.
