Best Practices – canonical url for child products pointing to parent

Hi,

I’m using the canonical url on WooCommerce shop pages to point to a single parent source.
The source is a marketing page outside of Woocommerce. The shop pages are all variations of the product.
My goal is to consolidate all the SEO to the parent page.

There is duplicate content on each page but each page is a little different.
I have reviews and star ratings not the Woocommerce product page however the parent is a normal WordPress page which won’t display review or star ratings, does this matter?

Is this a good way to use canonical url?

Should the different page Schema be the same category for the Woocommerce variation as the parent product landing page outside of the shop in WordPresss?

Thanks
