I need to fix this, but how? Astra has no controls for product pages that include plugins and Elementor skips it.

I checked the source code, and it has break in-between modules, but should the space be so far apart?

Lot of scrolling before adding to cart or Customize.

How to close all that gap/space?

I have that same question. I'm following it 

I'm still fiddling with it. Oh what fun!
