i can see some of your CSS is being combined with Autoptimize.
But the rest of the style sheets from the many block plugins you’re using are listed under render blocking resources are not combined – and they’re being served from a CDN.
I would suggest you focus on one optimization plugin and have that combine as much of your CSS as possible.
The issue i still see is that you have a number of resources loading individually from a CDN. You may want to begin by disabling the CDN and just use one of the Optimization plugins to combine those CSS files.
