I'm no plumber, but I'll give you my two cents anyway.

The tubing cutter will leave a nice finish.

I'd cut out the section of pipe, disconnect it at the water meter, and
insert the valve that way. Sliding things back and forth is a bitch
IMO. You realize you'll get a flood when you cut into that vertical
section of pipe, unless you have some way of draining the water below
where you are going to splice in the valve.

I'd be careful with a galvanized cap. The meter has a compression
type fitting which you might muck up with a cap. Not sure if NPT
would work anyway. But I might be wrong--again, I'm no plumber.
Should only take a few minutes to do the repair. Maybe you can get a
helper to empty your bucket or whatever. Heck, I've stopped leaks by
whittling a wooden plug and pounding it into the leak. That'd work,
but then you might break the plug off and have a real mess on your
hands.

I think a compression fitting is fine in this situation. A bigger
problem for soldering than your leaking meter valve will be the water
dripping from above...when I did this repair I was replacing the
piping in my whole house so I had the luxury of dry pipes.
