Jupiter is hard to find. It’s orbit is ~11 years making it harder to measure and more time consuming. It’s pull on the sun is a lot harder to measure than a hot Jupiter, making the radial velocity method more difficult. We aren’t finding average systems. We are finding systems that are easy (and quick) to find using the methods we have available.

Harder but not beyond us. Per https://physics.stackexchange.com/questions/230973/how-can-w... at this point we would be able to pick up Jupiter and Saturn around another star.

Yes, but I don’t see how that is relevant. Your claim is that we aren’t seeing Jupiter/Earth type systems and so they are rare. The counterargument is that we aren’t looking for them, so we don’t see them. We don’t know whether they are rare or not.

Keep in mind that there's many more orbits that don't occlude a star than those that do. So there's some luck required, and likely at least 2 orbital occlusions (22 years) to be sure.
