Is it just weight that decides if something floats or sinks? Or is there more to it?
It’s all about density. If the object is less dense than the water, it floats. Otherwise, it sinks.

Right, and this is why a steel ship can float. The air inside lowers its overall density.
Archimedes’ principle explains it perfectly: the buoyant force equals the weight of displaced water.
