only getting outlet covers and cabinet "latches"

Our apartment has door handles, not knobs, so that part of safety kits are useless. None of our cabinets have knobs, so we can't use those semi ziplocky cabinet closeted won't work. I'm thinking I'll get those magnet cabinet safety things, because I like them best. Then, of course, outlet covers.

I know that's a while in the future of when we NEED it. But I like being prepared. Are those really all we need? Just to fix our lower cabinets and our outlets really?
