Pinn , sounds like you have a lot to offer the right woman. It's ok to emphasize highly educated and financially secure in an online dating profile, without getting into too many specifics.
It's hard for short men, and you're probably right, you may have a better chance with women who meet you organically in real life. I've mostly dated average to tall (to very tall) men but have known two very short men that I found attractive. Both were about 5'3", fit, highly intelligent (one was a grad student in physics teaching my sailing class, one is a documentary filmmaker). Both were confident and comfortable in their own skin and that was attractive.
