I used Uber...... Way easier, faster start travel and cost is all about the same.
Disney hotels have transportation front the airport in the Magic Express shuttle. You would have to ask the hotel where you're staying if they have the service. Probably some will have for a $$. There is always Uber, Lyft and Taxi service. If you are staying in a hotel in Lake Buena Vista the probability of a shuttle for traveling to places near by is high. Remember Disney has free ground transportation for everything Disney.
There are tons of shuttles, but I don't remember one that went to the airport.
You can ask the hotel. I don't know of any. I'd use Uber or Lyft
I don't recall seeing one, Uber is a very common way of getting around including to and from the airport.
