Combine all purpose flour, baking powder, and baking soda in a medium sized bowl.
Cream butter, cream cheese, sugar, and salt in a large bowl until light and fluffy, about 2 minutes.
Beat in eggs and vanilla extract until combined.
Add flour mixture, buttermilk, and chopped strawberries. Stir until just combined.
Pour batter into prepared pan(s). Bake for 50 minutes (if using two 7½" x 3¾" x 2¼" loaf pans) to 1 hour (if using one 9"x5" loaf pan), or until wooden pick inserted in the center comes out clean. If the top is browning too quickly, place an aluminum foil tent over bread.
Cool in pan for 10 minutes. Remove and cool completely on wire rack.
