And it's also never explicitly stated that meteorite impacts are common on Hoth, simply that there is a lot of meteor (not meteorite) activity in the system that confounds sensors.

If you look up the definitions of meteors, meteorites and metoroids, you will see that meteor activity takes place in the atmosphere and if the meteor doesn't burn up completely, there is also a meteorite to be found. So if there is high meteor activity, chances are high that there are meteor impacts that leave a meteorite.If it was just some rocks flying around in space, it would be called meteoroid activity.

I don't want to nitpick on these terms, but since I was very interested in astronomy as a kid, I knew these definitions so I assumed they used the term "meteor activity" according to its proper definition.

Maybe I was too quick to say it was clear that these were two different objects, but nonetheless, there is no plothole.
