Sure, they're a long way from us...but there are a great many out there in
our
galaxy and every object must be in orbit around a mass centre of some
kind.
Most do not appear to have moved much in thousands of years.

Should we not expect to see more movement than we do?
How would you go about calculating what to expect? Until
you do that, you can't say whether they move more or less
than expected.
...my question may be naive and the answer trivial... so please enlighten
me.
Bear in mind nearby stars are roughly in the same part of
the galactic disk so tend to share a similar mean motion.
However, your first point is the key one, they really are
a very long way away by everyday standards.
