Delete Home page title and Change font of page title

I wanted to delete the page title on my home page, but it seems that if I do that it also deletes the name of the page on my primary navigation menu. Is this possible?

Also, is it possible to change the font of the page title? When I highlight the page title and go over to the editor and click “block: it says “no block selected” as if it cannot be edited. Thanks for any help.
