More particles and more interactions - QED is only electromagnetism, which is the easiest interaction to work with. The strong and weak interaction are more complicated, and then you also have to add the Higgs mechanism.

Yeah, that Higgs mechanism. I've heard it "gives mass to particles", and I've seen that sombrero graph, but it might be forever beyond my grasp.

I thought this explainer by PBS Spacetime was a pretty good overview of the Higgs mechanism. They go more in depth than “particles bump into the Higgs field” without going too deep.
