There seems to be 1 cab firm at the airport and the cost into town is £24. If you get to share the cab with others it cost £16.

Getting the hotel to ring one on the way back to the airport cost £19.50 but always ask.

For rental car bookings, two of the major agencies you might contact are Europcar and Hertz (especially if you are traveling extensively in the U.K., as these both have many U.K. destinations, and you can often leave your car at a different U.K. location than the one you picked it up from).

Europcar has two Cardiff locations, one of which is at the airport:
