What is the best way to display a large number of reviews in terms of SEO?

Question

Search Engine Optimization

If for some page (product, service, place) a lot of reviews are written, let's say several hundred - how best to display them for the maximum positive effect on SEO promotion and why?
Display all in bulk on the same page? Do an endless upload? Break reviews into pagination? Should I make a canonical on the first (main) page when paginating, should I do noindex on the rest, should I remove the main content about the service/organization on other pages or leave everything as it is, changing only the comments themselves? In general, please explain your position, why you think so, as detailed as possible.
No matter how much I searched, everywhere they write completely different opinions. It’s just that comments are like quite valuable units of unique content and I would like to get the maximum benefit from them in terms of SEO and traffic.

Display all in bulk on the same page? Do an endless upload? Break reviews into pagination?

I like the implementation of comments in the product cards of M-Video:

1. 15-20 pieces per page - for PS indexing
   
2. Pagination pages (reviews hidden on pagination pages are NOT indexed by PS). As an option, pagination can be implemented so that it expands by clicking the “View 20 more of 101” button
   
3. Feedback is displayed first based on user votes (by usefulness)
   
4. The remaining 15-20 according to the "freshness" of the date
   
5. One of the reviews from the "Reviews" tab is broadcast to the "Description" tab, which has a different URL
   

What would I change in this circuit:

• the most useful review was not duplicated on other product tabs. Now they have the same review "Useful review" is broadcast in two tabs of the product card "Reviews" and "Description", which have different URLs. Those. we get an internal double. It's easier to take any review that is not indexed and place it on the "Description" tab and add microdata with the review to improve the snippet
  
• add sorting on the "Reviews" tab, similar to DNS. This is of course not related to indexing, but improves behavioral and usefulness
  
• I would not do the ability to comment on reviews, although everyone decides for himself whether such a feature is needed / not needed
