<a href="https://cloudflare.com" rel="nofollow ugc">CloudFlare</a> is a popular CDN service. They caches static files like <code>.jpg</code>, <code>.css</code> or <code>.html</code>, but they doesn’t cache dynamic pages generated by WordPress without <a href="https://www.cloudflare.com/features-page-rules/must-use-page-rules/" rel="nofollow ugc">Page Rule</a>.
Once Page Rules are set, for exmple, <code>https://examle.com/article/*</code>, every single page will be cached(of course, your permalink structure should be like <code>https://example.com/article/2019/01/01/POST_ID</code>).
This plugin hamecache provides cache control feature. If you update your article, hamecache automatically flush related caches on cloudflare edge location.

Page cache plugin by Hametuha. Use cloudflare for distribution.

The plugin is an improved version of the “Cloudflare Page Cache” plugin. The plugin does not cache pages for logged-in users by default. You can disable caching for some URLs and for users with certain cookies (use the constants BYPASS_COOKIES_EXTRA and NON_CACHEABLE_URLS_EXTRA for the settings). 
For the plugin to work, you need to have a Cloudflare account with special settings. To purge the cache by the button, you need to set Cloudflare API settings in the plugin (CF_EMAIL – From https://dash.cloudflare.com/profile, CF_API_KEY – Global API Key from https://dash.cloudflare.com/profile, CF_ACCOUNT_ID, CF_NAMESPACE_ID). 
In the Сloudflare account, you need to create a worker, for details go https://github.com/palessit/cloudflare-cache-page. The plugin can preload cache on Cloudflare.
