So how do you propose to make those adjustments - by:
• manipulating the paragraph before/after spacing; or
• manipulating the paragraph line heights,
or both?
Do be aware that whatever you do to the first and last paragraphs on a page could affect the previous/next page if those paragraphs span a page break. Changing the line heights will certainly do that, whilst changing the before spacing will affect the previous page and changing the after spacing will affect the next page.
You may also be interested in minimizing paragraph last-line wrapping as part of your approach. For that, see:
