Which cms is easier to make a site with paid content (video courses)?

Question

CMS

In terms of design and content, everything is quite simple there, but it will be necessary to fasten billing, a user's personal account, limiting access to video courses depending on payment, as well as the possibility of P2P video communication.
It is clear that all cms have some modules, but maybe someone has come across a similar one and can help with specific advice - which cms and which modules are suitable for these purposes.

Answer 1

This is not a simple and not standard functionality, you have to do it manually.
Therefore, it is better to immediately take a flexible tool, like drupal or modx.

Answer 2

In opencart, downloading of materials after payment is implemented out of the box.
