Choice of CMS. What to choose to create a portal?

Question

CMS

Possibility of implementation:

• article can be with rating and comments
  
• The ability to give access to post articles and their moderation
  
• Create a seller card with reviews, ratings, photos, and videos of his product.
  
• the ability to create a catalog of sellers (their selection, accounting for advertising)
  
• creation of seminars by sellers on their product, both paid and free, and receiving a percentage for this
  

You need something like Avito, only with user profiles and their ratings similar to Yandex.Market. a seller card (person) with his material photo video prices, reviews rating + WordPress opportunities for creating articles with content and reviews, a small discussion.
