0W-20 is ok for daily use, especially if there are short drives and winter driving involved.
For summer only and heavier track abuse 5W-30 also can be considered, which may retain oil pressure at high rpms better imho.
It's mentioned in manual/handbook, that "If SAE 0W-20 oil is not available, SAE 5W-30 oil may be used. However, it should be replaced with SAE 0W-20 at the next oil change". But as to what type of driving what suits better, imho as per above. Then again you worded as "occasional" .. imho then just don't bother with choice and go with 0W-20. I'd care more about brake pad choice and suspension alignment, then engine oil type.
