Cloudflare APO Configuration and Limits

Team
I have two questions:

  1. Settings of APO with Litespeed cache. Litespeed is managing the page caching, and asset optimization. Will APO work. DO I need to switch off or switch on any setting.

  2. I saw a worker limits on APO, do these limits have anything to do with Traffic. Like my site has almost 1 million page views in a month, So, Will APO limits or Workers limit there will hinder that? What exactly these Worker limits are in terms of website traffic.

  3. After enabling the APO, will I get the benefits of full page caching?
