Ideas for a central CMS?

If you're not trying to integrate it with any existing code, and / or it's going to be the bulk of the site and / or you have not commenced on writing a bunch of existing code already - then I'd recommend you go with an existing CMS - it'll save you much pain and time. Drupal, Joomla, Deki, etc - most are written in PHP and all are designed to be extended.
