By far your best solution is to use LED lighting. You can use solid colors, but the 300 LED multicolor sets are the best and offer the ability to change lighting for different moods. These LED strips are mounted with a sticky tape that is on the back, but I recommend adding silicone or some other adhesive to make sure it stays put.
If you are electronically inclined and know how to use a soldering iron, these 300 LED strips can be cut at pre-marked lengths and connected together to form segments that can cover other areas, like your bar back all from the same controller. The strops are coated with a soft plastic, so you must remove a small amount of the coating in order to solder 4 wires to interconnect the segments. They come in 16 foot sections and if you don’t need that much, just hide the extra or black out sections with black plastic tubing.
If you cut the strips, you will need a light 4 conductor wire that you can probably find on Amazon. Four conductor Telephone wire is best, stranded, not solid, 22ga.
