Combine strawberries, 3 tbsp. honey, and cornstarch in small saucepan over medium heat. Simmer, stirring until fruit releases its juices and clear, thick glaze forms, about 5 minutes. Cool completely (it will begin to set; break up with spoon before adding to cream cheese mixture).
Using electric mixer, beat 1/2 cup heavy cream until firm peaks form. In separate bowl, beat together cream cheese, remaining 2 tbsp. honey, and vanilla. Beat in the strawberry mixture. Using a spatula, fold in the whipped cream.
Spoon the filling into crust; smooth surface with a spatula. Cover with plastic wrap and chill overnight or until firm. Garnish with sliced strawberries, if desired. Top with whipped cream before serving.
