H1 color, size and link

Hello,
I searched a lot but I didn’t find any solutions.
On pages and post built with advanced editor, I have heading title in header area next to breadcrumbs, but I can’t remove the link pointing to itself.
On posts built with standard editor (I’m testing Enfold on an old website I need to restyle, so I have thousands of standard post and I can’t switch them all to advanced editor manually) I’ve nothing in header (I don’t have a blog page, but different pages for certains categories) and I have post title as h1, but inside page content and with the settings from advanced style.
So I’d like the following:

• removing any link pointing to itself from single post/page title
• removing “blog” in breadcrumbs (well, since I’ve not blog page, I have something like Home/ /category/post while it should be Home/category/post
• having all post title in header instead of page content, even if they aren’t built with advanced editor.
• avoiding any possible h1 duplicate
• being able to edit categories titles instead of the standard Archives for

Is it possible? Thank you
