Agreed that the black marks look like they will polish out.

For the marks by the rear hatch I’d probably try with a rust converting paint like POR15, I believe they have a tintable version now that you could color match. For the bubbles area you could try Webb’s approach or spot sandblast down to bare metal and repaint the panel. Full disclosure, I do basic bodywork but defer the hardcore stuff to the pros. I’m not patient enough to be a good paint and body guy.
