Is there a plugin \ CMS to work with data?

Question

CMS

Can you please tell me if there is a plugin for Wordpress or a separate CMS (not a cloud one with a monthly subscription, but a server version) to create a manager's workplace?
Those. in the backend you create and edit the frontend page, on which managers (having separate access rights) would start users, add data to the table (s).
And the CMS itself built graphs based on these data, gave out statistics, made selection and sorting in tables, showed busy days in the calendar, etc.
Those. so that the backend allows, without special programming knowledge, to create pages and operate on data (as in a database) introduced by managers.
From what I dug up for WP:
- gravity forms (as a convenient means of adding data), but does not allow them to operate.
- tablepress (very limited functionality)
It is clear that WP is primarily for a blog, but still.
Perhaps there is an alternative?
Thanks
