Depends on what you're wanting to do. I haven't used Uber to go specifically, but I've gone many times in the past. I mean...it's a mall. It's a big mall to be sure, but I don't usually want to spend my Disney time going to a mall when I could do that back home. However, if there are stores at Florida Mall that you don't have back home, or if you want a day away from mouse ears, then go for it.
