Combine 2 pounds quartered strawberries, ¼ cup granulated sugar, and 2 to 3 tablespoons lemon juice in a large bowl and toss to combine. Set aside to macerate while you make the biscuits.
Line a baking sheet with parchment paper and heat oven to 400°F. Place 1 tablespoon lemon zest and ¼ cup of the sugar in a large bowl. Rub between your fingertips until the sugar is aromatic.
Add 2 cups all-purpose flour, 1 tablespoon baking powder, and 1 teaspoon kosher salt and stir with a fork.
Add 8 tablespoons cold unsalted butter (cut into pieces) and use your fingers to rub the butter into the flour mixture until it forms pea-sized pieces.
Drizzle in 1 ¼ cups cold heavy cream and mix with a fork until combined. (Dough will be sticky.)
Form the dough into 8 large, tall mounds using a large spoon or ice cream scoop and space 2 inches apart on the prepared baking sheet (the taller the mounds of dough, the easier they will be to slice in half). Sprinkle the top of the biscuits with remaining 1 teaspoon sugar.
Bake until the bottoms of the biscuits are deeply golden and the tops are lightly brown, 15 to 20 minutes.
Combine 1 ½ cups cold heavy cream and 2 tablespoons granulated sugar in the bowl of a stand mixer fitted with the whisk attachment and beat on medium-high speed just until stiff peaks form (do not overwhip), about 90 seconds.
Split the biscuits in half crosswise. Spoon strawberries over the bottom half and top with a dollop of whipped cream. Finish with the top biscuit.
