I have CG in the family...

That is probably true for inter-service transfers (navy/af/army pilots) who want to transfer to the CG or join the CG reserve. Not true for entry-level pilot applicants.

A word of caution about CG OCS. Last time I heard, if you want a CG commission you apply for that and attend OCS. Only after you are committed and in OCS do you find out what you will be doing in the CG. You MIGHT get a pilot slot, or you might end up in charge of maritime compliance...inspecting recreational boats for life-jackets and fire-extinguishers. This may have changed, but you need to find out for sure.

If you want to be a pilot DO NOT join the service without a guaranteed pilot slot. Honestly in your shoes I would pursue any military pilot slot you can get. The other services will give you a guarantee for pilot training, and if you really want to fly for the CG, do it in the reserves after your military stint.

I would also look into ROTC scholarships...the XC thing will help with that, and you can do both sports and ROTC.
