The consenus here seems to be that such objects are, in fact, more
prevalent. We just cannot observe them unless they do pass close to the
sun.

We're more likely to observe them if they're brighter, and being
closer to the Sun helps in that regard. But generally, no, it
shouldn't make any difference if they're particularly close to the
Sun. Just being in the inner part of the Solar System (roughly, inside
the orbit of Jupiter) should be all that really makes much difference.
