Store Settings → Shipping is only for orders you post. Pickup and local delivery have their own page, Pickup & Delivery.
Shipping is completely optional. Plenty of shops never post a thing, and that’s a perfectly normal way to run a shop.
The Right now box tells you what shoppers are being offered.
Shipping only appears at checkout for products marked I ship this. Set it in the product editor under Getting It to Your Customer. Anything left on Pickup / local only stays pickup, even in the same basket.
Pricing by size? Give each product its size in that same section. A product with no size uses your fallback price.
