minor feats - something like, "Honest Looking" adds +2 to Persuasion/Deception checks but -2 to Intimidation. People tend to trust you because you just look trustworthy, but this also means they don't feel threatened by you."
Given that they'd be basically background freebies specifically for character creation and available only at that time, and also within the scope of 5e's bounded accuracy, I would keep those benefits to +1/-1, but in general, yeah; I like these as minor perks that are a springboard for character flavour, directed by the player ands told to the game, for it to then use. (Tie this in to my other suggestion for an in-universes character defining progression as part of the tutorial that helps you tell the game who you are and where you're from, and you've got something beautiful, in terms of ability to characterise yourself to the game)
