Follow up.... I tried the manual movement of the switch and it still
made the water hammer noise. It feels like on the switch that there's
no slow transition between on and off, it suddenly shuts the water.
Just to be sure..... the noise I hear comes from 1 location in the
basement, it's of the water pipe rubbing against the joist for the
floor (sounds like a rattling/rubbing noise as the pipe shakes for a
second or two). Is there a new ballock I can buy that closes slowly
(do they wear out and now mine closes suddenly or something). I hate
to put too much time/money into this if its only caused by the toilet.
Why would it suddenly start up?

It is my experience that they all close quickly by design so that there
is a clear distinction between open and closed so you don't end up with it
almost closed.

I suggest you work at the input end. Partly close the inlet valve.
That should take care of it. The last time I checked the instructions for
my toilet it had a specification for how long it should take to fill the
tank and advised the installer to adjust the valve to allow it to fill in
that time.

Your water pressure may have gone up a little and that may be the real
reason you are now having a problem. Throttling the intake valve should
take care of the problem.
