Hello,
1) You can change menu font via menu element settings https://prnt.sc/26sc12h , the same with body and headings, there is no need to hardcode that. But you use CDN cache on your site https://prnt.sc/26sc1pr So, after any style changes in theme options you need to clear your CDN cache. Log in to your CloudFlare account https://www.amtradingoutlet.com/wp-admin/options-general.php?page=cloudflare#/login to allow us to clear the CDN cache and apply changes.
2) You can switch to the default type of my account page in WooCommerce > Settings > Account https://prnt.sc/26sc6f4 if you don’t like the new one or translate the new account texts in the XStore theme and XStore core plugin translation files.
Regards
