Choosing pizza flour, yeast & fermentation is really a choice about how you want dough to come together. Do you need flour built for Neapolitan-style pizza, a sourdough culture with tang, a dried starter with recipe help, or yeast that mixes straight into ingredients? The useful shortcut is to pick the dough-making role first, then compare flavor direction, preparation steps, and listed price. That keeps a flour purchase from being compared as though it were interchangeable with a fermentation starter.
Quick take
Start with flour if your fermentation plan is already settled. Choose a sourdough starter when culture and flavor are central to the bake. Instant yeast makes more sense when direct mixing and a streamlined routine matter most. The two sourdough choices then separate into dried and live formats.
Listed-price comparison
The prices span $6.17 to $23.99, creating a $17.82 spread. That gap matters because the selections serve different roles: a 3 lb flour bag, sourdough starters, and a 12-pack of instant yeast are different ingredient formats.

SAN FRANCISCO SOURDOUGH PIZZA Dough Yeast Starter, Sally

At $6.50, SAN FRANCISCO SOURDOUGH PIZZA Dough Yeast Starter, Sally offers a San Francisco sourdough direction in dried form. It is double pulverized for quick activation, has a sour flavor, and includes 10 recipe files covering pizza dough and other bakes. That combination is the reason to choose it: you get a starter format plus a broad recipe starting point. The limitation is the dried format, which adds an activation step before dough-making. Choose Sally when recipe guidance and sourdough character matter more than a direct-mix yeast routine.
Sourdough Pizza Starter Heritage San Francisco

Sourdough Pizza Starter Heritage San Francisco is the natural fit for a live-culture route. It includes a step-by-step activation guide and recipes, while its stated character is sour and tangy, with pizza dough or crust described as having big holes. Choose it when a heritage San Francisco starter and guidance are central to the project. The limitation is flavor direction: sour and tangy are prominent, so bakers seeking a milder, less noticeable sourdough profile may prefer a different route. The 200+ year heritage story adds context, but flavor and process are the more practical deciding points.
Instant Self-Rising Dry Yeast

At $23.99, Instant Self-Rising Dry Yeast is the convenience-led choice for a baker who wants a packet format and fewer preparation steps. Its finely milled granules are intended to mix directly into ingredients without pre-hydration, and it is presented for pizza dough, bread, cake, bagels, and croissants. That direct-mixing instruction is the reason to choose it when dough preparation needs to stay simple. The limitation is its $17.82 price gap above the $6.17 flour; it is also a yeast choice rather than a sourdough starter.
King Arthur 00 Pizza Flour Neapolitan Style

At $6.17, King Arthur 00 Pizza Flour Neapolitan Style is the focused choice for Neapolitan-style, thin-crust, or artisan pizza dough. Its fine 00-style grind is described as smooth and workable, with use in either a pizza oven or conventional home oven. Choose it when fermentation is already settled and flour is what you need to select. The limitation is scope: it addresses the flour side rather than supplying yeast or a sourdough starter. Wheat is listed as an allergen, a concrete consideration for kitchen planning.
Final recommendation by use case
For flour-first baking, choose King Arthur 00 Pizza Flour Neapolitan Style. For a dried sourdough project with recipe support, choose Sally. For a live heritage starter, choose Sourdough Pizza Starter Heritage San Francisco. For a packet-based yeast routine, choose Instant Self-Rising Dry Yeast. Start with ingredient role, then decide whether flavor, activation, or direct mixing best matches your pizza dough proofing plan.
