I don’t think you’ll get full cpanel access with A2’s Managed WordPress Hosting. They give you enough access to do whatever you need to without all the advanced items.
Pretty much every page within cpanel has a link to documentation for that page/features. Here are the main categories.
Below are sections I’ve used over the years with an asterisk for ones I’ve used frequently. PHP is likely something you’d never need. I’ve had to use it when trying to install software other than WordPress because some required an older version of PHP than what was running. PHP 8.2 is what’s running right now and any good web host will update it themselves so you don’t really need to worry about it.
