Help! How would you spell this name?

For reference I am British, and so these pronunciations are how it sounds in my accent. I want the name to be pronounced like AH-na/ AR-na, like at the end of Liliana/ Eliana, or the start sound of Arlo. How would this best be spelt? I like either; spelt ‘Arna’ it means strength, and ‘Ana’ means grace. I think Ana might get confused with ‘Anna’ though? (Pron. like Hannah) which isn’t how I’d prefer it to be said. Does anyone know any Arnas/ Anas? Thanks for your advice ❤️
