In a large bowl, mix warm water, sugar, and yeast. Let sit for 5–10 minutes until foamy.
Add flour, salt, and olive oil. Mix until a sticky dough forms. Knead on a floured surface for 8–10 minutes until smooth and elastic (or use a mixer with a dough hook).
Place dough in an oiled bowl, cover, and let rise for 1 hour or until doubled in size.
Preheat oven to 425°F (220°C). Grease a 9x13-inch pan with olive oil. Press dough into the pan, stretching to fit.
Use your fingers to dimple the dough. Drizzle with more olive oil. Scatter cherry tomatoes, sun-dried tomatoes, and garlic evenly over the surface. Sprinkle with oregano, red pepper flakes (if using), and flaky sea salt.
Bake for 20–25 minutes, until golden brown and cooked through.
Remove from oven, sprinkle with fresh basil, and let cool slightly before slicing. Serve warm or at room temperature.
