What's the difference between removing all blank lines and consecutive blank lines?

'Remove All' deletes every empty line. 'Remove Consecutive' keeps one blank line between paragraphs but removes extra ones.

Does it remove whitespace from content lines?

Only if you enable 'Trim whitespace'. It strips leading and trailing spaces/tabs from each line.
