Hi there,
For what it's worth, pagination is a source of contention for many SEOs, so you're not alone here
I think part of the reason for this is that there isn't a perfect answer and I'm yet to see consistent, definitive proof of any one answer being right, particularly when it comes to different types of websites. As you say, for a blog, it may not be that useful anyway. Whereas for an ecommerce website, it's probably more important but even then, users are not likely to click through to hundreds of paginated pages, but search engines may need to crawl them.
Anyway, the timing of your question is funny because earlier I came across this tweet thread from Patrick Stox which does a great job of laying out the options. I'd recommend taking a read:

Ultimately, keep in mind what your goals are - I imagine driving more traffic to key pages on your website. I'd also look at how things are performing at the moment and make decisions based on that. If your paginated pages are getting lots of traffic, you may not want to tinker too much with that. If they aren't, then you can make changes far more easily because you're not risking too much.
I hope that helps a bit!
