Of course most uploads to Amazon are for ebooks, but to submit for printed books to Amazon it is best to upload PDFs. I have in the past asked about altering calibre's method of doing a printer's offset but, apparently, there is something extremely difficult in restructuring its margin capabilities for Amazon's proprietary requirements.

But if you are publishing you have source. Epub isn't source.
If publishing PDF, then simply edit all the content in LO Writer, with appropriate paragraph, character and page styles, headers, footers, page number etc. Then export a perfect PDF direct from LO Writer.
Epub to PDF is only for own use. Madness for publishing. If I ONLY had epub source, for some reason, I'd export docx or RTF and edit as odt in LO Writer.
Any method of cropping PDFs is also only for own uses, say to read on a larger eInk or tablet.
Calibre is fine for managing ebooks, and conversion of real ebooks (re-flowable).
The common reason for me to crop or adjust background on PDFs is because they are PD scans of old PD books or magasines.
k2pdfopt, ImageMagick or the GIMP are the best solutions for that.
The workflow would be a bit different if scanning myself to do OCR or doing OCR of PD scan to create a wordprocessor file, then proofed via epub. I'll rarely do that as I'd only do it to re-publish and I can't imagine taking that effort for likely no return.
My 11" tablet is fine for PDFs, and only a 14″ version of it would be better. I don't need to spend hours making them work on a 6″ to 8 ″ eink or a phone screen.
