I've generally been adopting more machiavellian, discreet characters which is a nice avenue as it allows exploring subtle undertones and having outside of action as a focus. Though I have quite gone full spymaster just yet, there's a nice contrast option against that of an extrovert and socially active person as it creates a personal conflict which is another great post tool. I generally try and avoid thinking what would I say/do, but rather what would someone like that do/think which is a great feeling when you pull it off well enough that it seems realistic.
