Multiple Errors with Product Snippets and Asking Google Not to Crawl Pages

Hi, I am having a problem with Google Search Console giving me error messages about product snippets on my site.

I have landing pages for all the products in a given category, and each product links to the individual product page. Google is telling me I am missing a name for these landing pages. The individual product pages have the name field, and they are indexed with no problem.

I also have a critical issue with “Missing Return Policy”, Aggregate Ratings, Price Valid Until, and several other issues.

I would like to explain to Google that the landing pages are not individual product; the scheme classifies them as webpages..

I would also like to know if there is a straightforward way of dealing with the reviews, return policy, ratings, et cetera without having to deal with each product separately. I have a return policy page, and I am not running sales, so I don’t know what to do at this point.

I am not particularly conversant with any actions that involve coding or inserting things into the page. I definitely prefer plugins that will do the job.

If I am not in the right place, I apologize and hope someone can help in plain English, not tech-ese.

Thanks for taking the time to read this.
