There is a feature called ‘Review workflow’ which allows you to have certain roles be able to review the news articles of other editors.
This is however a paid feature of Strapi, I’d be interested in that also.
Then for the subscription model, I don’t believe there is a simple plug and play implementation for that. Would be nice to have some plugin with which you can sell certain roles.
Video upload yes.
RSS feed not ootb, but should be a small feature.
Archiving content can just be done by adding a boolean field to the news collection type. Also quite simple.
