What is the best race/culture/background/class combination in POE1, POE2, and all of the DLC content, that makes the storyline more interesting? (Some Avowed Spoilers)

So I learned that in Avowed players with the War Hero have the option of making things more interesting by stating that the Envoy and Lodwyn were Master and Apprentice, comrades in arms, or ex-lovers.

And that got me thinking, what is the best race/culture/background/class combination that makes the storyline in both games and all their DLC more interesting?

According to this post from 4 years ago, the Paladin and cipher classes, the Island Aumana/Fire Godlike, and the Deadfire culture dialogue checks but would you say they add something to the story?
