I mean it's not shounen nor action, at all, but I'm gonna recommend Hyouka (not Haikyuu, this is something else). Also if you're looking for an action anime there plenty of shit I haven't given the time of day. If your looking for a good action try something like Solo Leveling, it's pretty entertaining. Action anime I will let the others to that because I have absolute dogshit taste in action.

TL;DR My recommendations are Hyouka and Solo Leveling
