Which CMS (or other solution) to choose for a file selling service?

Question

CMS

Friends!
The eternal question arose from the lack of relevance of my knowledge.
Tell me the ideal CMS from your point of view (or another solution) that suits the organization of file sales. We are just designers, and up to this point we have administered a maximum of OpenCart and Magento at a basic level, and no matter how much we tried, we could not fit it to sell files. We will sell archives with site templates, the closest analogue that we really like in terms of the way the work is organized - one and two . To solve the problem, we make the following requirements:
1. Convenient multilingualism. The future store is designed for Russian and English-speaking audiences, with product descriptions in these two languages ​​at once.
2. The readiness of the solution specifically for the sale of files. That is, when, for example, you can easily disable all unnecessary CMS functionality, such as filling in the delivery address when making a purchase. Or, fields already ready for filling in the product card to indicate a link to view a demo of this product.
3. The most simple ordering from the point of view of the buyer. That is, the ability to simplify the checkout from the admin panel as much as possible.
4. A large number of payment acceptance modules designed for ours and foreign ones.
5. Files will be paid and free. Free ones become available after registration.
6. It was possible to view the store without registering, but it was impossible to download free files.
