The short stem can shorten the distance between the handlebar and the seat, so that the riding posture will stand up a bit.
Generally, downhill cars use short stems, so they have good maneuverability;

In contrast to the long stem, the distance between the handlebar and the seat is long, and the riding posture is low. The vehicle feels very combative. It is more common on racing bicycles.

Or we can do with your requirement on this;

The short stem of the bicycle is too short and not suitable for tall people. It cannot guarantee that the upper body can be stretched perfectly. It has a feeling of shrinking. The handlebars and knees have a certain safety distance. Even when standing and stepping on, the knees will not hit the handlebars. .
The long handlebar can ensure a certain safe distance between the handlebar and the knee, even when standing and stepping, the knee will not hit the handlebar.
The longer the upper tube of the bicycle stem, the more stretched the upper body and the easier it is to exert force, but the problem is that the center of gravity is shifted forward and the control performance is reduced, which is suitable for racing competitions.
On the contrary, when the upper tube is short, you can straighten your upper body and get good maneuverability and vision. Of course, you will not be so comfortable in exerting force.
