There really shouldn't be a one size fits all approach to hitting.
Guys with good speed and limited power should 100% be focused on putting balls in play and minimizing strikeouts.
Guys with worse speed and better power need to be focused on putting their best swings on hittable pitches. Unless you have Frank Thomas level plate discipline, this is going to result in more swings and misses, but you're going to get full value on your SLG from those swings.
