Absolutely agree with you on the h1 font. It's massive and is inappropriate typography in my opinion. I seen a title that was three lines long because of the mega-font.

Nothing can be changed with CSS (site-wide). The dropdown color can be modified by changing the "main" color in the Theme Designer.

This edit to Help:Navigation states links can be added to the "Explore" tab so perhaps this could be a solution for that issue (or the Toolbar). I'm not sure how Fandom is going to let us add links though.
