Saddle fore/aft

The most common confusion in this area is using the saddle to fix an upper body problem. It doesn't work, and it makes the lower body fit worse in the process.

Here's why it backfires. Your saddle position sets where your hips sit over the pedals, and your saddle height and knee angle are dialed in around that exact spot. Slide the saddle forward to bring the bars closer, and your hips come forward too, which undoes the leg fit you just set. You'd close the reach and break your saddle height in the same move.

The saddle stays where your legs want it; the bars move to meet your arms.

The rule: Saddle fore/aft is for hip position over the bottom bracket. Upper body position is for arm reach and torso angle. Two separate adjustments, two separate purposes.
