When you say "my family is important to me," you are saying that you hold your family close to your heart -- that they hold an important place in your life.
But if you say "my family is important for me," you are implying that you somehow benefit from your family or your family connections.

The simple explanation is that "important to" is something you value,
while "important for" is something you need, or that will help you in some way.
