Some Australian input:
As a wealth-adjacent kid growing up in a boho posh part of Sydney, my playmates included Ursula, Amberwren, Ophelia, Cleo, Kimberley, Melissa, Amanda and lots of Catherines. The boys tended to have short, plain names such as Greg, Mark and Michael.
Now I live in Melbourne and am still wealth-adjacent in a boho posh/medical specialist posh/bankster area. Kids around here are called Millie, Molly, Maddy, Mia, Maya, Audrey, Abigail, Isobel and Florence. DD's school has heaps of Sophies and Siennas. Boys are overwhelmingly Hugh and Hugo, Lachlan and Angus, plus a few oddities; my little neighbour is Atticus. I also know a Weibo, named after the Chinese word for the internet 
Australia likes to call itself a classless society. It's not, of course, and names are just one way in which the classes distinguish themselves.
