As others have said, you can buy an adapter that has a threaded copper end
and a CPVC-compatible other end to make the transition.

Also, you can probably find a place the secure the CPVC pipe itself to a
joist or stud using an ordinary metal bracket that is used to secure pipes
to walls and ceilings. You probably don't need a dog-eared fitting.

I am redoing the run from my shower valve to my shower head on the pool
side shower.

Originally it was all copper pipes in and out. However, the copper pipe
from the shower up the exterior wall, then a 90 degree elbow, then three
feet along the soffit is exposed piping. Now that I have the inside sheet
rock removed for other work, I am thinking of removing the exposed copper
pipe and run the pipe to the inside wall from the shower valve, and up and
over on the inside of the wall and above the soffit, so the entire pipe
run would be concealed.

Originally, the copper pipe was soldered to a coupling that has a stub on
one end and 1/2" male thread on the other end. I cut the copper pipe and
unscrewed the coupling. So now the top of the valve has a 1/2" female
threaded outlet.

I am thinking of using CPVC pipe instead for this concealed run. It's
code approved and a lot easier than copper with no need to solder. I will
do all the fittings using CPVC fittings except at the end of the run I
will probably use a sharkbite drop ear 90 to secure the CPVC to a piece of
wood for a ceiling mount shower arm. How would I connect the shower valve
to CPVC pipe? Do I need some coupling to go from a female threaded 1/2"
to CPVC? Is there a sharkbite coupling that does that or a special CPVC
coupling that does that?

Thanks,
