CMS

How is a CMS suitable for an internal enterprise portal, as well as plugins for it, with the ability to fill in a database (corporate documentation, supplier cards, etc.)?

Answer 1

Which CMS is suitable... with the ability to fill in the database (corporate documentation, supplier cards, etc.)

- None. Just something self-written with an increased level of security, logging of user actions and other goodies, because what you listed is valuable information for any business and a trade secret.

Answer 2

in general, most
bitrix CRM systems, for example,
depend on what exactly is needed. The portal is nothing

Answer 3

As Anton R. wrote above , a self-written engine is better than ready-made solutions in a box.
In any case, it is better not to use open-source engines like WP, Modx, Joomla.
If there is no time to write your own, then mb Sharepoint will do
