One thing I've always been curious about - if a site receives third party content, but also is assigned copyright to that submitted content as part of the T&C of submission, does that make it first party content? I would hope not, as I think the assignation of copyright does not imply the immediate ability for the site to review the content of that submission.

I'm not a lawyer, but no. Section 230 has nothing to do with copyright. It only asks if the content was created by a third party. Licensure doesn't change the creator.
