What modules to use for specific tasks in MODX?

Question

MODX

Hello!
Hello. We are trying to understand what CMS to take as the basis of the project. We study 3 systems in parallel: MODX, WP, Joomla.
The task is to get away from custom solutions as much as possible, in favor of ready-made assemblies, plugins, modules, including paid ones.
During the analysis of MODX, we managed to collect the following solutions to our problems:
Regionality of the site (site.ru/spb or spb.site.ru)
modx.ru/novosti-i-stati/article/91
Multilingual interface As far
as I understand, it is implemented according to the principle of regionality
Custom fields
The ability to add is implemented in the system
Unsolved problems:
1) Is it possible to set the logic of behavior through custom fields? For example, there is an ID field, a variable is entered into it in the admin panel, based on it, an API request is executed and we get the data that the API returned when entering the page? The logic may be different, depending on the categories/categories of articles.
2) Is there a separation of user rights? For example, copywriters have access only to their articles, editors - everything, administrators - system settings.
3) Integration of additional solutions - conditionally, if we want to build our own online store based on MODX, and we know for sure that not a single ready-made solution will suit it, how costly in terms of money and time will such an implementation be? Pages will have their own logic, their own fields in the database, which are needed for this task.
4) Organization of e-mail / sms mailings with different templates within the system users
5) Flexibility of work within one URL
Conventionally, for the first half of the year there will be articles on the URL, then the articles move to another URL address, while the URLs of the articles themselves do not change. And in place of the already "old" URL, we expand the custom directory. How easy is this to implement within WP?
6) Multilingualism of articles
In order to edit an article, it would be possible to enter one article in different languages?
It seems to be everything .. Thanks to everyone who can master at least a part :)

Answer 1

1) You can ask - what you write in the snippet will do.
2) There is a division and it is quite simple to set up.
3) There are many ready-made plugins for online stores, but in general MODX is not suitable for this business.
4) There is a plugin.
5) MODX has symlinks.
6) Multilingualism is a weak point, it is implemented with crutches.
