Print Book File | PDFs for KDP Upload | Export Options | Pages or Spreads?

I'm ready to generate two PDF files of my 6-chapter print book for KDP upload. My InDesign book file is set up as shown below to ensure reading coherence and follow convention. Given the intentional method for page layout between left and right pages, and Chapter 1's special separation to make the text start on page 1, what export options do I need to check for proper KDP upload under Export Adobe PDF > General > Export As? Pages or Spreads? Will KDP:

1. adjust to meet my intent?
2. adjust as they see fit and not meet my intent?
3. reject with an explanation so that I can adjust and resubmit correctly?
4. reject without an explanation so that I must adjust in a guessing fashion?
