Preheat oven to 400 degrees. Line a baking sheet with parchment paper. Set aside.
Mix flour, sugar, baking powder, and salt together in a large bowl.
Once combined, cut in the butter and cream cheese with a fork or pastry cutter until the mixture resembles coarse crumbs.
Whisk together heavy whipping cream, egg, and vanilla extract. Slowly add the wet ingredients into the dry ingredients, and mix until just combined.
Add in strawberries, and mix until just combined.
Turn the dough out onto a lightly floured surface, and sprinkle more flour on top, if needed (if the dough is too wet--the strawberries can release a lot of juice). Form the dough into a circle, about 1/4-1/2" thick, and cut into 8 even triangles.
Place scones on baking sheet, and lightly brush the tops of each scone with heavy whipping cream.
Bake for 15-16 minutes, or until the tops are golden brown.
