Melt 2 ounces of high-quality white chocolate in the microwave at 20 second intervals, stirring in between. Once fully melted, set aside to cool.
Soften the cream cheese in a medium microwave-safe bowl by microwaving in 10-15 second intervals. Stir in-between intervals. When the cream cheese is very soft (but not hot), use a hand mixer (med-low speed) to beat it smooth, about 1-2 minutes.
Add 1/3 cup sugar, 1/2 teaspoon vanilla extract, and a pinch of salt and beat on med-low until sugar is fully incorporated/dissolved, about 1-2 minutes.
Add the cooled melted white chocolate and beat until combined, about 30-60 seconds. Add 1/2 cup of the reserved (cooled) strawberry sauce and beat until just combined, about 30-60 seconds.
Use a spatula to gently fold in 2/3 cup of Cool Whip until fully combined.
