He leído algunas preguntas sobre longtablecómo hacer que se ajuste al ancho de la página, pero no he tenido éxito. En el ejemplo, la tabla se ajusta al ancho de la página pero sale de los márgenes especificados. MWE adjunto. ¡Gracias!

Creo que la tabla se vería mucho mejor si (a) usara 'raggedright` en lugar de alineación centrada y (b) usara espacio simple. Además, examine la exactitud de su afirmación de que "la tabla se ajusta al ancho de la página". En mis cálculos (que se muestran en el código siguiente), el ancho de las columnas debe ser estrictamente inferior a 8 cm.
Ah, y tenga en cuenta que longtablelos entornos se centran automáticamente, no es necesario encerrarlos en centerentornos.

Personalmente, usaría ltablex(hace tabularxuna "tabla larga") y luego las tabularxcolumnas (como quieras usar tabularxde cualquier manera). Aquí hay una imagen del resultado (con showframe, para que pueda ver que se ajusta al margen):
