I always use a mineral first for the first 2000 miles, though tbh it's very old fashioned since the oil companies reduced the amount of zddp a modern fully synthetic will break in perfectly.
Just don't labour the engine for the first 1000 miles, use revs instead, they need so little bedding in compared with older engines, I'm at 5000 rpm on a light throttle for short periods by 500 miles.
5W30 is fine, I use 5W40 personally in my dads zetec but 30's fine.
