slickstack VS moosh

I recently came across SlickStrack, which is a utility for setting up WordPress on Ubuntu LTS. It sets it up with Nginx and some other configs, by which it attempts to enforce some best practices with regards to speed and security.

I know this page is like 5 years old and I cannot comment anymore (closed):

......I never heard about that mod_PHP popularity was rising again compared with FPM pools. Is that totally fake news or that was true temporarily during 2017 only?

My understand that even cPanel hosting is still mostly using PHP-FPM with Apache and .htaccess (2021). Is there any case that using mod_PHP or disabling .htaccess can be faster than PHP-FPM or that is totally wrong.

For Nginx I know FPM is really the only option. And lots of arguments about ondemand, I see a lot of tutorials saying dynamic is better, but on this config file (PHP 7.4) and it says

"ondemand is best for the majority of VPS servers (contrary to many online tutorials) .......only incredibly high traffic servers should use dynamic after tuning settings?

To be fair, in this case, SlickStack is the nginx configuration. It's maintained by nginx professionals and is readily available to view in their github repo. He didn't think it was necessary to spell it out in his forum post.
