I run a sourdough bakery with my partner, as it happens. Although I'm not a baker, coming from a mathematics background I'm the one most focused on process and quality control. We don't use any commercial yeast so I've picked a few things related to targeting different flavors using the same starter.
We use different temperature profiles during proofing for different products (we have fancy proofing fridges where we set temperature profiles over a 12 to 36 hour period depending on the product). Low and slow is good for certain types of bread, or pizza base. But not so much for a brioche or croissant dough.
I personally love slow fermented, heavy rye based sourdough, but lots of our customers don't and the bread we sell most is a classic white sourdough fermented comparatively quickly at higher temperature for a lighter and less sour taste. It's still very slow fermentation compared to commercial yeast, of course.
The proofing temperature profile for this bread isn't as simple as "start warm and gradually cool down" (i.e. the warm oven method), but that is a reasonable approximation for a home baker.
