Thanks for considering using Foxy. Since we allow you to build and manage your products and product pages right in Webflow, you get to piggy back on all of the SEO features they offer.
In relation to Google Shopping, it's just a matter of getting your CMS Collection data converted to an acceptable feed for Google. You'll need more than Webflow's RSS Feed functionality, but I think you should be able to get what Google is looking for by integrating and converting data with Zapier.
