Subdomains are treated as independent websites and don’t inherit the equity of the main domain.When you blend different architectures, you will get contextual tag collisions. From the SEO point of view, I always recommend keeping the blog in a subfolder to spread the page equity and allow the whole site to benefit from the extra content.

Strictly speaking a sub-domain will be treated differently than the main domain. My pragmatic view is, that unless you have massive domain authority and shed loads of traffic on the existing main domain, it becomes all a bit of a theoretical discussion. This quote is back from 2012, so things have might changed since then, but it resonates with me:
They’re roughly equivalent. I would basically go with whichever one is easier for you in terms of configuration, your CMSs, all that sort of stuff… Both are on the same domain overall and so it’s really a question of which one is easier for you. Whichever one makes you happier I’d go ahead and do it that way.
