2 main guns (red) and a seaplane for most battles. Could be 2 main guns + star shell / night scout / searchlight if you want the extra night battle cut-in rate or to decrease the enemy cut-in rate.

2 sonar + depth charge or sonar + depth charge + radar for pure ASW. Main gun + sonar + depth charge for mixed.

It's basically situational, but those are the setups I find myself using the most.
