Best configuration settings WordPress website, Hosted on Siteground with Argo & APO

My WordPress website has the following setup: hosted on Siteground, which has its own caching plugin called SG optimizer, Cloudflare free version but paid for Argo and APO. Before I started using Argo and APO the performance was great, but now the performance went down a lot. I also had an issue with images not showing up but I resolved that by switching off WebP image generation within the Sitground optimizer plugin, and that might not be the best solution, so if there is a better solution, please let me know.

I would like to know what the best configuration is. To summarize my setup:

  • WordPress website with donation plugin that handles payments through Stripe.
  • Managed Hosting (Grow Big) at Siteground
  • Cloudflare free CDN
  • Cloudflare Argo
  • Cloudflare APO
