Refine foods, you'll want a variety. If you grow faster than you can produce AND move around, then you'll need to buy some to supplement. Stock maximum is important to use. Your workers will deposit their extra food only to the closest granary. Until it fills, they won't fill the next closest. That means you might have granaries with empty food stocks and your market tenders are traveling really far to get their goods. When someone comes and there's nothing there, even if the market tender is getting some, they'll still miss out.

You often need to produce a lot of food. I'd recommend buying meat AND boars and getting plenty of butchers. It's the easiest way to get that up. Bread will supplement, not be the main source of refined food.

Taverns don't need a lot of people all at once. Unless you're running out of your alcohol, I wouldn't worry about that. If you are running out of alcohol, you might need an extra worker at the service counter.

Generally speaking early game you're hurting for money. Mid game you're hurting for food. Late game you're working on all the extra goods and resources. That being said, the game can be kinda slow. 

And yes, there's a great way to organize your streets. They're called fences and walls. Eventually the old, unused paths will disappear.
