TO do or Not to Do- posts and pages

I am managing 2 websites that are likely to have equal number of posts and pages,-Blogs and Brain exercises.

Another website has blogs and products, this presents a challenge.

The issue is deciding which to publish as post and which to publish as blogs, one issue is hiding privacy policy from the list of posts even when it is on a page, with No Indexing and No follow.

Thanks in advance.
