Sorry, but personally, I don't find any of them beautiful! Nice enough though and there are far worse options I've heard.
Amelie- I need to read it twice to check its not actually Amelia
Eliana- Agree that there are lots of vowels and its a mouthful. I always think of liana, the climbing vine!
Aria- A pretty name, but also the name of a music award in Australia, so similar to calling her Brit, Grammy or MTV.
