The credit card owner's credit score is not, and can not, be affected by the user's credit score. Likewise, the user's credit score is not, and can not, be affected by the owner's credit score.
The user's score is affected by the presence of the new card on their report. If it's an old card with a high limit, the user's score will go up. But the user's score is completely unaffected by the owner's score.
So, if your wife's card is old and high, your score will go up a little - because of the card, not because of her score. But even if it goes down a little it won't have any affect on rates lenders offer you.
You and your wife's scores will not be affected by adding your daughter as a user, but her score will go up because of the new card.
