Beyond settings API – more "complex" admin pages

Hello, I’ve studied settings API and used to build settings pages for plugins and themes. I can line up text inputs, checkboxes, radio buttons, textareas, and select pretty well so far.

But now I need something more advanced to manage rows of data from custom tables other than wp_options, data that doesn’t make much sense to manage inside wp_posts with custom post types.

These more “complex/advanced/custom” admin pages would need to:

– not only requires a single submit button, but some add/edit/delete buttons for example.

– some ajax to make things more like the buildt-in edit.php for Posts

– show lists of objects pulled from custom database tables.

Anyone could direct to me to the canonical and developer friendly way to accomplish this?

Thank you
