How can I really make my Facebook profile private to people I'm not friends with?

So I've done all the privacy settings that I can find yet my Facebook profile still seems fairly public to people I'm not friends with. When I click on certain profiles of other people I haven't friended, there profiles are completely private. You can't click to enlarge their cover photo or profile picture, and you can't view any of their pictures. Also their timeline is blank; it doesn't show any of their activity. I want mine to be just like that. I know it's not like that because I've seen it on a different device when I wasn't logged in to my own account. I've been through my privacy settings multiple times and nothing seems to help. What do I do to make it private like the profile I described? And yes, I realize that social media isn't meant to be private, and if I can't make my profile as private as the ones I have come across, I will just inactivate it.
