Yes, you are right, standing waves is the exact model that is used. All the measurement problems with e.g. location are just a consequences of that, some properties of a standing wave may be "smeared all over" the wave, like its location. And some interactions with the wave will change it. Quantized things are just standing waves of different order or "frequency" in a confined system. You just understood 80% if quantum mechanics.
