Estoy intentando (sin éxito) reducir el tamaño de la CONTRACTED_Byrelación en este modelo ER utilizando eltikz-er2paquete. Naturalmente, escala la altura con el ancho, pero preferiría que la altura fuera más corta. ¿Hay alguna manera de lograr eso? (Lo siento, esto no es tan mínimo como podría ser, pero decidí replicar la figura que tengo).

Puede cambiar la aspectproporción de ese nodo con la aspecttecla. De forma predeterminada, en el estilo está configurado 1. Aquí lo he cambiado a 2.

No puedo compilar tu código porque me falta tikz-er2, pero al mirar tu código, el cuadro de "CONTRACTED_BY" es más grande debido a la longitud del texto. Supongo que si redujeras el tamaño del texto, el cuadro también sería más pequeño. Puedes probar lo siguiente:
\node[relationship] (contract) [below=of project] {\small CONTRACTED\_BY} edge node[above right] {N} (project);
