Start all 4 screws with a screwdriver then finish with a power drill. Low torque setting if you're really scared.
Your problem with power tools is that you're scared of cross-threading. Fair enough, start 2-3 threads then tighten down with a drill. Small handheld drills can't provide enough torque to strip inserts or any sort of thread. Once the screw head bottoms out, the drill can't turn anymore.
Now if you use a Dewalt 120V drill at drilling torque, then of course you're gonna strip inserts. Use your common sense.
