1. My site is a Wordpress site and had tags and duplicate subpages (like abc.com/page/2). I've gotten rid of them and blocked google from accessing them.
I found the opposite works.
Index - the first 200 words of the latest articles, many regulars don't click around.
Category - the first 200 words of the latest articles in that category, desc order. many visitors want articles from one subject.
Archive - the first 200 words of each article broken down by month, asc order. Usefull to find older content without clicking through vast amounts of pagination.
+ The article itself which is where Google sends most first timers.
No canonical, Google indexes the article itself for the keywords and OFTEN gives the site multiple results from those other pages. If duplicate was an issue I'd be smacked silly on that site. It makes sense for visitors so I don't care what G thinks, thankfully they didn't maul me with a bear yet.
