I am considering doing an FUE, and later on need I recognize that I may want another transplant, won’t the FUE cause my donor availablity to be less as compared to having the strip transplant?

I think that you must put the various surgeries that you may want into a Master Plan for your hair loss. If you are not going to be very bald, then an FUE solution is not an unreasonable one. The long term yields for an FUE may have to do with donor density, but for strip harvesting, I have exceeded 10,000 grafts over more than one surgery. With regard to your query, I do not believe that anyone really knows whether FUE will cause your donor availability to be less than that of the strip procedure, but I would personally doubt that FUE will yield more hair for transplantation than strip harvesting. There may be a role for combined FUE and strip at the end of the process.
