PHP framework with editable admin panel?

Question

CMS

I choose a framework for the project.
The entire frontend will be in angular, respectively, the backend is only required to give json data from the database and templates.
The most important functionality - the user fills out a form (let's call it "application"). The application goes to the admin. There, the moderators confirm it, supplement it, add notes, comment on the progress status, etc. After confirmation, the application can be displayed on the site.
Also on the site there will be news and separate pages edited from the admin panel.
In order not to completely write a bicycle for news and user accounting, I am looking for a suitable system that already has an admin panel (at least with users and a blog / news) and where this admin panel will be easiest to expand with its functionality.
Alternatively, a bare cmf with a good admin plugin that can be easily extended is probably suitable.

InstantCMS is a lightweight engine, although the documentation is not so hot, but in half an hour you can write both a module and a component, both back end and front end ))

Answer 2

Well, the same Drupal can quite easily do everything that you wrote here. You have to smoke it for this, yes ...
