Hello, Rana,
Thank you for reaching out to us.
1/ If you want to edit the archive page (Shop or Blog or Category) using Elementor/WPBakery you need to use Elementor Pro/WP Bakery Pro, the default Elementor/WP Bakery does not have such an option. If you have Elementor Pro/WP Bakery Pro, contact their support to get assistance.
Please check the available settings in Theme Options > WooCommerce > Shop > Shop page Layout. For example, content on the Shop page can be added using a static block as a shop banner. Product design can be edited via Theme Options > WooCommerce > Shop https://prnt.sc/6Sce13bc5452
2/ Font family can be changed via Theme Options > Typograhpy or using custom CSS code.
