Advice on choosing a name with a potential conflicting nickname

Need advice! We’re expecting our baby girl in July and would love to name her Eleanor. Id assume nicknames for her would be El/Ellie. The only issue with this is my partners first cousin goes by Ellie. I know her full name is not anything similar, but I don’t remember what it is bc pregnancy brain.

Would it be wrong to pick this name? They’re not very close cousins, but close enough that I could see potential issues from her mom (his aunt) or her sister.
