The center of mass of the sun-Jupiter system is just outside of the surface of the sun, so I think there would be a lot more than a 30 foot wobble. I'm not up on my multibody celestial dynamics to figure out how that would affect the orbit of the earth around the sun.

(I was shocked that the barycenter was that far from the center of the sun).

I just looked this up, and you’re correct. I, too, am quite surprised that the barycenter of the Sun-Jupiter system is NOT located somewhere within the sun.

30ft is just an avg, there can be more depending on the alignment of all the planets. Very complex system.
