Is GraalVM a good option for this?

Yes and no. Graal Native Image doesn’t work for spring, since some of the jvm functionality wrt. class loading don’t work yet (I think). Also native image has lower throughput due to the lack of profile driven code optimizations.

The Spring team and Graal folks are working on full support. I believe the main angle is to ensure the annotation-based model will work smoothly[0]. Another is to introduce a fully-functional model (Spring Fu/Kofu [1]).

Bear in mind, a lot of what Spring -- Spring Boot in particular -- gets charged with is beyond its control. It's an entrypoint to the vast Java ecosystem, much of which is also incompatible with Graal native images at the moment.
