Is there a single word that means “helpful and interesting”?

Question

I’ve been reading a lot of applied psychology and find myself frequently describing an exciting idea as “both interesting and helpful”, to connote that the idea is intellectually fascinating and also has clear and interesting implications for how it could be applied to one’s own life, and/ or personal growth, and/ or understanding self or others. Is there a single word - or a better phrase - that connotes both of these things?

Answer 1

A single word that may come close is
