Often orgs like local CFF chapters, Hospital fundraisers, ect. like to have poster children (so to to say). Unfortunately there is quite a bit of compassion fatigue at the moment and a great many places need volunteers, but not necessarily for CF. Through my work with United Way and the VOA I have met and done work related to CF issues, like social & environmental justice and health reform. So it could be good to broaden you search parameters and see if you could bring a unique lens of experience pertaining to the issue or activity of voulenteering. Right Now there will be need for back to school stuff and disability is something that schools may need help organizing efforts around (ensuring the nesecities for people of different ability in this time of budget cuts) often acting as a advocate for things like that is especially.
Also there are things like meal on wheels or other differently abled/limited ability services that you could help with in you community. usually the United Way's or what have you's will have people who can help you find oppertuinites appropriate to your skills.
Do keep in mind that sometimes people just need help and orgs do not care about what special insight or abilities you have as much as the fat that you have arms and legs to help with labor... it's not glamorous, but necessary and usually fun. I have met many interesting people doing grunt work at food pantries, non-profits, and shelters.
I guess what I am trying to say is that advocating for CF is great, but you are also human so doing work for the common welfare or for broad topics like disability policy and funding is equally valuable.
