Which CMS to choose for a large project?

Question

CMS

The main tasks that CMS should solve
Work with content

1. Convenience of working with a large volume of articles for a copywriter who enters them
   
2. Using different article templates
   

Categories of articles

1. Integration of additional fields within prepared templates
   
2. The ability to integrate third-party solutions into articles (for example, downloading additional materials via API)
   
3. Working with functionality
   
4. Ability to integrate additional solutions, such as deploying a large catalog of services, receiving and using data via API
   

Categories

1. Specifications linked to categories (a set of properties for filtering on the front)
   

Technical requirements

1. System performance regardless of database size
   
2. Ease of editing project templates
   
3. Separation of user rights administrators, editors, visitors
   
4. Working with 5 languages ​​in one article
   

These are the basic requirements. I liked MODX for flexibility, but for working with 1000 articles, it confused with its functionality, working with articles is convenient in WP, DLE, but there is not enough work flexibility. I don’t want to write from scratch, because there will be a lot of bikes.

Answer 1

All this is in Wordpress. For five languages, put some kind of WPML and go.

Answer 2

I, as a WordPress evangelist, will try to be as careful as possible. WP - will pull. If you need to start as soon as possible. For multilanguage in your context, Multisite is best, there is a good paid plugin for this business - do not be stingy, take it. For fields and metadata - Advanced Custom Fields 5 Pro. Also, the paid version, don't be stingy. Even along the way, there will be a need for other, smaller plugins. In general, it can be done.
But! Considering that we live in the real world, where not everything is so smooth (and, as experience suggests, everything is usually very, very uneven), I need to finish a lot / cut a lot for myself. This is all real, and you can do it qualitatively and for yourself on WP, but the amount of work will be considerable, the complexity is also on the level. Accordingly, the real cost of development and further support will be very round. IMHO, in this case it is better to write for yourself on some Laravel. Or, ideally, first build it quickly on WP and a couple of paid plugins, load the editors with work, collect all the comments / edits / suggestions, etc. And in parallel to write your platform from scratch, given the parallel real experience.

Answer 3

Try Drupal v7: it's just right for what you've described

Answer 4

I also write on Wordpress. From experience, such a site would never make an order on it. I could start doing it myself, but if I order, then only on a system ready for such functions.
If there are real catalog functions
1. The ability to integrate additional solutions, for example, deploying a large catalog of services, receiving and using data via API,
then you usually immediately need
+ payment
+ payment accounting
+ then affiliate program (referral links)
+ product placement by users and accounting for these products in their personal account
, I would then do it on Bitrix, it is done well there and the speed of the site out of the box is also good.
