Jump is a dex/acro skill not a strength skill.
Is it? Then I apologize for making wrong conclusions. I based my response completely on what it says in PHB.
PHB page 175.
Athletics. Your Strength(Athletics) check covers difficult situations you encounter while climbing, jumping or swimming. Examples include the following activities:
- You attempt to climb a sheer or slippery cliff, avoid hazards while scaling a wall, or cling to a surface while something is trying to knock you off.
- You try to jump an unusually long distance or pull of a stunt midjump.
The section about acrobatics seemed to be more about balance or tricks like somersaults, flips, rolls etc
