To me it's always a bit like the chicken and egg ... you need energy to create a force and a force transfers energy which came first who can say :-)
I just got registered. Read your initial post, and now this one.
I agree with your initial post. There are only two types of energy: potential and kinetic. The energy locked inside any body is potential as far as the body is concerned. The speed of the body constitutes its kinetic energy. A transfer between these can be regarded as a change from potential to kinetic and back.
Why not force be regarded as a reactions to energy at the particle level, and spilled over to higher levels when the particles integrate. Then there can be three types of forces: one from kinetic energy, the second from potential energy and the third from the motion of a particle having potential energy. And there are the suitable candidates: gravity, electrostatic force and magnetic force.
