Help with picking a girl name for our girl/boy twins

Hi, we're expecting boy girl twins in early May and we're having a hard time coming up with names. We're not even thinking about middle names at this point. We've used a baby name app where you swipe like a dating app, books, online lists, our ancestry, AI, etc...

For the boy, we are leaning towards Emmett but we're still open to other ideas. Other boy names are Elijah, Elliott, Matthew and William but I think Emmett is the leader currently.

For the girl, we're having a much harder time. We like Evelyn, Audrey and Grace but we have family with those names. My wife likes Ivy, April and Autumn. I like Charlotte and Reilly. We don't really have any clear winners.

We have Al/Av/Am/J/El/Sh names in our immediate family so all those names are out. Last name is a McC... So names like McKenzie are out too. We would like to have the name be a similar length or maybe the same number of syllables but probably not the same first letter.

This is in the US but we looked at names from various European countries like Italy, Norway, Germany, and the UK (all family ties).

We don't like names like Ashlyn, Xander or Maeve. We would ideally like names where you can tell someone the name and they've heard it before and could spell it easily for someone (Emmett with two m's and two t's, for example) but also don't know many others with that name. I realize some of the names listed are not super unique but in our realm, we don't know many of them.

Any ideas are greatly appreciated! Sorry for the wall of text! I think we both feel a lot of pressure naming two humans for their whole lives, and those names possibly having an influence on their personalities.

Edit: thanks for all the suggestions already! My wife isn't even awake yet so I can't even deliberate with her!
