One thing I don't often consider during my bouts of "let's mix DND with my latest fandom obsession" is the difference between what class my blorbos would be and what class they would play (at least for their first game, we all know players tend to vary after a while)
They might be the same, but they also might not be.
For example: I think Joe Liebgott would be a fighter, probably dex based. Not just because he's from a no magic setting, but because he doesn't strike me as faithful enough to be a paladin, or as having the inclination to study enough to become an artificer. He does however have enough smarts to be a battle master.
As a player, I think he'd either go for maximum tanking with a moon druid/bear totem barbarian multi class OR a spy master rogue build for investigation and espionage (it'd make him feel like he's in one of his favorite comics).
Similarly, I think David Webster would be a wizard. I know bard seems like an obvious choice because he studied literature, but I don't think he has the charisma for it, and wizard fits better with what we see of him in the snow imo.
As a player, though, I do think he'd go for bard: it fits his artistic inclination, his general ability for intense studying AND his cautious nature by allowing him to stay out of harm's way if he plays his cards right
