If proper CPR involves compressing the chest so much such that the ribcage might break - doesnt that breakage risks a bone puncturing the heart?

That’s incorrect.
Someone might be not breathing for a number of reasons. Most likely however, when you find them unconscious & not breathing on the street it’s for cardiac reasons. And then a defibrillator is the one best treatment for that (if the heart has a shockable rhythm that is).
