Preheat the oven to 325°F (163°C) and prepare a mini cheesecake pan or muffin tin with paper liners or silicone molds.
Combine graham cracker crumbs, granulated sugar, and melted butter in a small bowl until mixture resembles wet sand.
Press about 1 tablespoon of the crust mixture firmly into each cavity and bake for 5 minutes, then cool slightly.
Beat the softened cream cheese in a large bowl until smooth, then add granulated sugar and blend well.
Add eggs one at a time, mixing gently and scraping bowl as needed, then mix in vanilla, sour cream, flour, and salt without overmixing.
Fill each crust nearly to the top with the cheesecake filling and bake for 15-18 minutes until centers are set but slightly jiggly.
Cool cheesecakes in the pan for 10 minutes, then transfer to a wire rack to cool completely before refrigerating for at least 2 hours.
Whip heavy cream with powdered sugar and vanilla in a chilled bowl until stiff peaks form, then fill a piping bag.
Pipe a swirl of whipped cream on each chilled cheesecake, top with a hulled strawberry pointed side up, and finish with a small whipped cream dot on the strawberry tip.
