Preheat oven to 350°F (175°C). Line the bottom of a 9-inch springform pan with parchment paper, grease the sides, and wrap the outside snugly with two layers of heavy-duty foil.
Process graham crackers into fine crumbs. Combine with sugar and melted butter until mixture resembles damp sand. Press firmly into the bottom and 1 inch up the sides of the pan.
Bake the crust at 350°F (175°C) for 10 minutes until golden and fragrant. Cool completely on a wire rack, then reduce oven temperature to 325°F (163°C).
Beat softened cream cheese on medium speed for 2-3 minutes until completely smooth. Add sugar and beat until fluffy. Mix in sour cream, vanilla, lemon juice, and salt on low speed.
Add eggs one at a time, mixing on low after each addition just until incorporated. Do not overmix. Fold the batter by hand to catch anything at the bottom of the bowl.
Pour the filling over the cooled crust and smooth the top. Tap the pan on the counter 3-4 times to release air bubbles.
Place the foil-wrapped pan in a roasting pan and add hot water until it reaches 1 inch up the side of the springform pan. Bake at 325°F (163°C) for 60-75 minutes.
Turn off the oven and leave the cheesecake inside with the door closed for 1 hour. Then prop the door open slightly for 30 more minutes before removing to cool completely.
Remove the cheesecake from the roasting pan and foil. Cool completely on a wire rack, then run a knife around the edges and refrigerate for at least 6 hours or overnight.
Cook two-thirds of the strawberries with sugar and lemon juice until broken down. Stir in cornstarch slurry and cook until thickened. Remove from heat and stir in the reserved strawberries. Cool completely.
Remove the cheesecake from the springform pan. Spoon the topping over the top just before serving, allowing some sauce to drip over the edges. Slice with a sharp knife dipped in hot water.
