For this situation, 1/4 turn angle stop valves are the way to go. Less parts, last longer and more reliable that a multi-turn compression type valve.

If you're doing repairs on CPVC, you'd be better off replacing all of your plumbing supply. CPVC gets brittle after about 15 years because the material becomes more rigid with age. If it's never moved, it's fine. But when you go to change a shut off valve, they're easy to snap. I've had it happen on a regular PVC supply when removing the supply hose. That was a messy day.
