I like to use a freeze proof yard hydrant.
I set a 4x4 treated post in concrete and use galv pipe strap to the post.
These also have a provision to lock them off.
The water shutoff is below ground with a drain.
When the handle is in the shut position, it opens the drain and the water in the standpipe drains out.
Open the valve, and the drain closes, and the water comes out the nozzle at the top.
