Agree with the advice on finding one you and yours are most comfortable with.
Do any of the options have crazy ammo prices compared to the others?
I would recommend everyone stays 'qualified' on whatever they have, both from a range perspective and maintenance perspective, so I would go with whichever one 1) best to fire for you 2) cheapest to shoot on the regular.
You are talking home defense, defense of the castle, so whatever it is, you need to be darn sure you and yours can handle it. Range, range, range...
