Combine the sliced strawberries, granulated sugar, and lemon juice in a bowl. Toss well and let sit for 20–30 minutes until the strawberries release their juices.
In a large bowl, beat the cream cheese, mascarpone, powdered sugar, vanilla extract, and strawberry preserves until smooth and creamy.
In a separate bowl, whip the heavy cream until stiff peaks form, then gently fold it into the cream cheese mixture.
Quickly dip or drizzle the ladyfingers with orange juice or strawberry juice.
Arrange a layer of ladyfingers in the bottom of a 9x9-inch baking dish.
Spread half of the cream mixture over the ladyfingers.
Add half of the macerated strawberries and their juices over the cream layer.
Repeat the layers with the remaining ladyfingers, cream mixture, and strawberries.
Cover and refrigerate for at least 6 hours or overnight until fully set.
Slice and serve chilled, garnished with additional strawberries if desired.
