Toss the strawberries and lemon juice in a bowl. Place the strawberries in a colander over the bowl and let the lemon juice drain into the bowl. Reserve.
Thoroughly oil and flour a 16-cup bundt cake pan, making sure you get all of the crevices.
Preheat the oven to 350 degrees Fahrenheit.
Whisk together the flour, baking powder, baking soda, salt and tapioca flour in a bowl. Set aside.
In a stand mixer, or in a large bowl using a hand mixer, beat the sugar, butter and lemon zest for two minutes. Scrape down the bottom of the bowl midway.
Add the yogurt, the reserved lemon juice from draining the berries, milk and the vanilla extract and strawberry extract (if using) to the bowl and beat them in.
Add all of the flour mixture and mix over medium-low speed until just combined. Scrape the bottom and sides of the bowl with a spatula to make sure everything is evenly incorporated.
Dollop about a fourth of the batter into the bottom of the prepared bundt cake pan and spread it evenly.
Add the strawberries to the remaining batter and mix them in. Then scrape the batter into the bundt pan and smooth the top with a spatula.
Bake 50 minutes or until a toothpick near the center comes out dry or with a few dry crumbs sticking to it (not wet batter). Remove the cake from the oven, place on a rack to cool for 30 minutes, then unmold and continue cooling on a rack.
