Help with middle names!!! 😱

Elizabeth
So baby girls name will be Ellie but can't think of a middle name that flows with it... My oldest really wanted us to name her Grace so I considered adding it as the middle name (Ellie Grace)  but then her initials would be E.G.G lol... Does it really matter what her initials would be? Help please and suggestions would be greatly appreciated!! 😫😊
