I'd suggest at pro level the strikers aim at narrow targets: bottom left, top right, etc.
Coaching youngsters in the past, I found if any were struggling it was mainly cos they were trying too hard to be too perfect, and the slight misses from imperfect strikes (eg. hit the post) affected them more, causing too much effort and subsequent worse results.
My tip was: "Just aim at the [centre of the] goal." Any mi****s are more likely to be on target and may possibly squeeze in the corner. Point is, they're giving themselves a greater chance of hitting the target.
Pro players hit it hard enough that even slight mi****s are powerful, although it also means wayward shots go further off target (ref: Redmond & Long). Aim at the centre, give yourself a better chance. As confidence comes back, accuracy can be narrowed down.
Even MLT said some of his best long-range goals were ones when he aimed at the centre of the goal and the ball then curved away from the keeper: vs Villa and Coventry (I think) are examples. It works.
This is football's equivalent of golf's "Just stand up and hit it" rather than over-thinking it, and it works for that sport too.
