I have not hobbied there yet since I am usually seeing family. I recommend using your Uber app, because you know what you will be paying. The taxis I took ones didn't have meters and will overcharge a gringo, especially from the airport. It's usually only about 20% more, but still. Some cabs have apps, but no need since you have Uber. They pick up on the upper level at the airport, but there are two lanes, so you have to keep an eye out for their license plates.
By the Gold Museum you can take the cable car up to Monseratte church. The restaurants on top of the mountain are inexpensive with a great view. I'd do that on Thursday if you can because it will be busy on Friday-Saturday.
I usually just take a hoodie. Bogota weather can change 4 times in a day. Hot, then wet and humid, then it clears. Can get cool at night. I recommend a hat because you can get red from the sun quickly, even when cloudy, because of the altitude.
You will have a blast. Keep us informed because I plan to retire there.
