I've heard lots of discussion around Google and hidden text. My problem is similar but involves links.
My website's footer is pushed for space at mobile screen size. I could really do with using display:none on about 3 of my footer links to save some space.
How would Google react to this from an SEO perspective?
Not a problem. Mediaqueries are made for these types of situations. As long as you dont use weird stuff (@media screen and min-width: 1px){ a{display:none;}), you have ntohing to worry about.
Simply rule of thumb: The user should see the exact same thing as bots. If a bot would mimic mobile view, is the content the same as for the user? Yes it is, no problem*.
