X can really stand for anything, such as wx in weather, mx in maintainence, or x in crossing. It's not used much, and when they picked it they probabally just used it to fill space. When you think about it, it wouldn't really sound any better if other letters were used.

As Ywg_jy correctly pointed out, Canadian airports codes are 4 letters, each beginning with the letter C. This dates to the time when the Canadian government was allocating radio callsigns. When they allocated callsigns to those in the form CYxx and CXxx to airports. (A radio callsign is just an identifier, like WNBC or KTLA) The 3 letter airport code for a Canadian airport is just the callsign minus the 'C' at the beginning. So Toronto's airport radio callsign is CYYZ and the 3 letter airport code is YYZ, just like Vancouver's is CYVR and YVR. It was just an adminstrative decision. Other countries used a different method to pick airport codes, this was Canada's.

The motto for Ft. Myers (SW Florida Reg) is "Ready to Serve the World. They have it written all over their website, and I think they have that code for that reason. Or maybe LoneStarMike is right, and they just figured out that their assigned IATA code worked out as an abbreviation for a cool moniker.
