Hi
I would say a 10w-50 is likely to be the best option, but it's worth fitting a temp gauge as if the oil stays under about 120C, then a good 10w-40 might be a better option.

The Nanodrive CFS is, on paper, the best oil available, but the Pro S, Red Line and CFS are really good oils, so all are good choices for your car.
A 10w-60 is likely to be too thick, so won't flow properly. This explains why a 10w-60 is rarely a good choice.

Certain tuners recommend 10w-60s as they seem to think the thicker the oil, the better the protection, but a lot of the protection oil gives is due to the way it flows, so if it's too thick, protection is reduced.
