Maybe more accurate to say that the standard model is just QED with more fields. But basically, yeah. QCD for example, involves the strong nuclear force (gluons) and "particles" with "color" (eg. quarks). QED is electromagnetic force (photons) and "particles" with charge. Vanilla QED just considered electrons (and by extension, positrons).
