I figure that given the rather extensive question that it does deserve some answer. I don't know if there is stack exchange on the history of science or physics, but that might in fact be a more appropriate place for this. The grandfather of quantum mechanics was Max Planck. His assumption that distributions of energy occurred in discrete units is what lead ...

The metal plate which is a target of the photo-electric effect can be analyzed as a quantum-mechanical system of pure electron states called "eigenstates", where each state has a wave function which is the product of a spatial distribution and an exponential (ossillating) time distribution: exp⁡(jωt)*ψ(x,y,z) Some of the states are bound states, where ψ(x,...

Your reasoning is quite correct, and you can see exactly this phenomenon in a photomultiplier tube. The photomutiplier tube uses very thin metal sheets, and when a photon strikes the sheet the primary photoelectron is emitted in the same direction as the incident photon and escapes from the far side of the sheet: The quantum yield for this process is ...

In the experiments for photoelectric emission, the light is incident on one face of the emitting plate, for example the anode, when determining the stopping potential. The electrons are emitted by this face of the plate. Why are the electrons emitted in the direction of the incident light, and not opposite to it? In this answer the energy momentum balance ...
