If your charging system is in good shape, there will be some charging going on at idle.

The whole engine, including the oil, heats up and will eventually get to operating temp.

Not if your engine is tuned properly. CO emissions are very low and drop to next-to-nothing once the cats warm up. I still wouldn't advise idling in a closed garage but it's not the big problem it was back in The Good Old Days.
