They are best used after development is done. You may want to look into full site caching, something like WP Super Cache. There are also several other full site caching plugin in the WP Repo
This is a self promotional plug: https://wordpress.org/plugins/blunt-cache/
It’s a fragment and object cache. There are also some other caching plugins similar to mine in the reply. The main difference with mine is that it uses filters and actions.
