What full page cache can I use for Magento 2 store on OLS?

[Vovkata]

Since the built-in full page cache in the Magento2 backend is not advised to be used on a production store (only for development purposes), and the other option is Varnish, what are my options to use FPC, for free, on OLS?

The LiteMage plugin is designed for LSWS which supports ESI, so it won't work correctly on OLS. If you still want to have some page cached, you might want to try cache rewrite rules, https://docs.litespeedtech.com/lscache/noplugin/installation/#basic-rewrite-rules
