I would also say that the campaign traits are not really a value calculation in the same way the feats are. They're meant to add color and help you as a player integrate your character into the town of Sandpoint.
The "best value" traits from a combat min-maxing perspective only add +1 to hit and damage to a specific type of enemy, so it's not like you'd be missing out on a lot if you choose "wrong." I put that in scare quotes because there really is no wrong answer here at all.
