Answer 3

And by the way, I use a combination of fastest cache & fastest cache premium & autoptimize plugins. I cache everything except CSS through the fastest cache. I use autopmize only for combining and optimizing CSS. I also set up critical CSS in the same place - https://jonassebastianohlsson.com/criticalpathcssg...
And I use autoptimize, since fastest cache cannot create critical css and Google complains - source: www.wpfastestcache.com/premium/optimize-css- delivery
