The soldier has to be Connie. His facial features, nose bridge, jawline etc and overall head shape match more to Connie (as well as the hair). You can see it's Connie's exact short hair, just had slightly grown.

While it's true Pieck must've taken a closer look at Jean when she lunged at Hange, she also passed by a house Connie was standing on and could've taken a glance at him.
