Starting a nano (14g) tank: fish options?

[ELBee]

I'd like to get a single, preferably showy, centerpiece fish for this tank. Something reef safe, as this will have coral in it eventually.

I could use recommendations! Ty in advance!

Flaming Prawn Goby pair.

Bangaii Cardinal or Ocellaris Clown Pair. A 6 Line Wrasse would look nice too.
