Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
Yes. You can create AMP pages that use the Layout canvas for content but there are a number of considerations.
Yes, you can use Drupal fields in certain parts of Acquia Cohesion.
It depends on the use case. For fields and their field formatters use a 'Field' element, for data without field formatters, use a token.
Yes, the component link field supports both internal and external URLs.
No, the entity browser does not work for component defaults as the entities are content, not config.
No site specific data is stored on the API.
