I tape for my own stuff. Makes life easier if you have to or want to replace the device hot at a later time. A little belt and suspenders. On commercial, I tape, unless ordered not to. For hotels, generally devices are not taped. And, yes, wire bent around the terminal screw.
I just wired a 100 yr old garage. I used 12 ga MC for rodent protection and some mechanical protection. 1" PVC conduit for welder circuit. 3/4 would have worked with juice to pull. 1" made life easier, and I pulled a 4th wiire for green, even though the receptacle does not have a ground terminal. If a future user needs a ground, it is already there, and hooked up at the panel. I used a lot of 4x4 boxes with 1/2" one or two gang covers. These allow a lot of future flexibility to add a device or an additional leg if needed.
I generally use 12ga and 15 or 20A breakers. I only use 14 with 15A breakers for low load LED lighting circuits. The 12 Ga everywhere is little more initial cost, but insignificant over the long run, for an additional safety factor.
In this install, only one 120v circuit may see a 20A load, the circuit for the table saw.
MC is cheaper to install, (faster) than conduit.
Worked as industrial/commercial sparky... non-union. My methods are a little belt and suspenders, and some may consider old fashioned, but I (or my employers) never had a call back because of my wiring. When you are in business, no call backs is a big deal. Difference between profit or loss sometimes.
