Heinrich covered it. Be a good masculine man. I won't repeat what he wrote though endorse it, but add some things.
First, figure out education while you have time to plan. This day and age unless you are lucky that means homeschool. Luckily homeschooling has advanced to an incredible extent. Your kid can even attend "online" making it easier than ever. Do the research.
If you end up homeschooling, look into social activities for your daughter. Classical ballet is my favorite. But make sure she will have activities with other friends. Trad meet ups during the week are also great.
For the teenage years, I love swing dancing for teens. Parents can chaperon easily because it's natural for all age groups to be there.
Eventually she will need to learn about computers. Set up a computer in the living area where it is natural and easy to see the screen. Avoid tablets and phones that she can take to her bedroom.
Make sure there is plenty of outside play time. Therefore ration computer time.
Set standards on chores. That is your job, as mama has a big mommy heart and is not suited for getting your daughter to toe the line. After you set policy and verify compliance it will make things a lot easier on your wife. At 4 she can help set the table and fold clothes. Make sure your wife is training her in home skills. As she gets older she should cook dinner at least once per week. Note little girls LOVE helping mama bake.
Have a weekly date night with your wife only. This will keep your marriage fresh.
Be playful with the wife. If your daughter sees Daddy chasing Mama around the house "patting" her on the bottom with a spatula ever so often, or you two get into a pillow fight, that's good for your daughter to see. Also don't be afraid to grab your wife and give her a kiss in front of your daughter.
Make sure real fights are done in the bedroom. Explain to your daughter that Mommy and Daddy love each other, but sometimes they have to argue something out. However since you are Catholics, you will always be married.
