For most expeditions almost any destroyer is alright. Most (but not all) destroyers have the same fuel consumption. If the expedition in question consumes ammo, then you should definitely use Mutsuki class. If you can afford the space, about 17+ destroyers is a good number. With that amount you can sparkle some destroyers at 1-1 while others are out on expeditions, and when the expedition destroyers run out of high morale you can swap them out ASAP, and continue doing expeditions, rinse and repeat.

For Destroyers, ASW differences between them is largely irrelevant. The base ASW stat adds very little, and can easily be ignored when picking a destroyer for ASW duties. I will note, however, that Verniy has the highest ASW stat among destroyer.

For Destroyers you want to sortie for grinding stages, feel free to use any of them besides Mutsuki class. I highly recommend Yuudachi Kai Ni, and Ayanami Kai Ni as they have a great cost to performance ratio.

For event maps, you'll want the best of the best. These are Shimakaze, Yukikaze, Amatsukaze, Verniy, Shigure, Yuudachi, and Ayanami.

And lastly, Mutsuki class have the lowest repair costs and times.
