Note that most are just flat bonuses to stats or received exp/jp/stat points, others change the required training to do something. Also some traits change the personality of the girl.
Note that the distribution in amount of traits linked to a specific zodiac sign is fairly balanced, but the mechanical advantages they provide are not really in my opinion. There are clearly stronger and weaker traits.
Now for the negative traits (these are not linked to zodiac signs):

Weak (-10 constitution/rank)
Note that here there are also stronger and weaker ones and I would advise against using them too much to min-max characters, but stick to what thematically fits. On the other hand you could improve some of your favorite girls a little, which will give you a greater sense of luck when you manage to buy or find her in-game.
I might be arsed to create a nicer overview in the future (some table or image), but for now this is it.
