In my opinion, Capulet is your typical angry controlling father. I like to think it's possible he is a drunk who after becoming rich cared for very little besides himself and maintaining his accounts.
I say this because in the beginning, he acts as if Juliet has a say in her choice to marry, but as the story moves on, he works really hard to make sure she marries Paris and tells her that she can hang, starve or die in the streets if she doesn't. I think he even gets abusive.
Lady Capulet is a typical rich woman who satisfies herself with prestige and social status. We see this as she encourages Juliet that a marriage to Paris would look good for the family. She actually does this beautifully in an extended metaphor comparing Paris to a book in Act I.
When Romeo talks to Friar Lawrence about marrying Juliet, we see that Friar Lawrence thinks Romeo has a girl problem. He worries that Romeo's motivation lies in his eyes, not in his heart when it comes to women. Thus, the difference is between lust and love. The Friar tries to distinguish this in Romeo but agrees to marry the two because of the potential benefit to the town's well-being if these two families can find a way to get along.
