Most fitting character build for good playthrough

I'm thinking of replaying BG EE and BG2 EE, and I'm wondering what would be the best character build for a good playthrough. I mean storywise of course, not in terms of most effective or easiest to play, for example for an evil character you could play an assassin trying to live up to Bhaal's legacy since Bhaal himself was an assassin when he was a mortal. Anyway, thoughts would be appreciated.
