A little or a lot. Generally speaking, wear and puncture resistance is the governing criteria for training tires. Rolling resistance and grip are important for racing. There is a world of tires that fit these criteria in various ways.

Tire size (diameter) needs to match the rim. Tire width needs to match the intended use and fit within the constraints of the frame/fork. I realize that's pretty vague. See
this page for details.

Yes: steel, kevlar, rubber, cotton, proprietary plastics, synthetics are all good.
Good for one purpose, may detract performance characteristics in other places. I prefer folding clincher tires (kevlar, not steel bead), high tpi casing and a puncture resistant breaker. Many tires fit within this criteria.

I believe you mean narrow.
I don't recommend anything in particular but I would expect a large percentage to be 23c

On car tires, the tread is often shaped to avoid hydroplaning. Road bike tires are narrow enough to make this characteristic unimportant.
