Regarding “List”: this is actually a table that you can create in different ways:
* If you register a Custom Post Type, such a table with all its options will be automatically generated by WordPress. See: https://developer.www.ads-software.com/plugins/post-types/registering-custom-post-types/
* But you can also use WordPress’ own WP_List_Table class to create such a table with completely custom content: https://developer.www.ads-software.com/reference/classes/wp_list_table/
* Or you can write it completely yourself in your own plugin or theme, using the IDs and classes used by WP_List_Table for individual elements.
How to integrate tabs in a settings page is described quite well here: https://nimblewebdeveloper.com/blog/add-tabs-to-wordpress-plugin-admin-page
