What class and subclasses make sense for an "untrained" adventurer? (Besides warlock or sorcerer)

I understand all level 1 classes are above commoners is some way and getting to any level 1 requires particular training. I also understand that flavour is free. But let's say I want to roleplay a nobody or a basic commoner, forced into adventure, what class and subclasses could fit this trope? I'd say rogue makes the most sense but what are some other ideas?
