Might that water hammer arrester be something I should be thinking about.
Or, should I call the faucet company and ask about how to rectify the

I'd do the water hammer arrester. My guess is that you replaced an
old, short handled faucet with a new, long-handled one, and now you
are essentially turning off the flow of water much more decisively,
hence, you now have a water hammer. It can happen anywhere you have a
quick closing valve.

So the solution is to close the valve more slowly.....
