I’m looking for the best options for powering sites under Drupal 8 and 9 when I install the latest version of Hestia for the first time. Until now I was using Apache2 with Ngnix as a static cache with VestaCP that I want to leave for a HestiaCP solution with the famous management of different versions of php.
Hestia uses php fpm as default now, there is no need to add or change the flag, also multiphp flag would just install each version from 5.6 to 7.4, currently you should be fine with running a default install, then add additional versions over the web server settings in the hestia interface.
