That means your server cached everything.
By default, wp-admin, wp-login.php, my-account, cart, and checkout pages should be excluded from the cache by Wordops installation.
When you using Cloudflare, please try this plugin https://wordpress.org/plugins/wp-cloudflare-page-cache/, it will trigger purge cache accordingly with Cloudflare when you clear the cache by Nginx helper.
Also, remember to disable the page cache in the plugin of wp-cloudflare-page-cache, and let the fastcgi cache be working only server.
So, Redis cache is not recommended if you use FastCGI cache with Cloudflare.
And, overall: fastcgi cache + cloudflare + Nginx Helper +wp-cloudflare-page-cache
that should be fine, but you need to test in incognito mode and make sure it works as expect
