We met a few Paiges at DS1's toddler groups/nursey/school. DS is now in his 20s, so I would say that Paige is dated. It puts me in mind of Taylor, Elisha, Kayleigh, Lauren, Mercedes, Abbie, Shannon, Mia, Ashleigh, Bethany, Chloe, Courtney, Amy and Libby - all contemporaries of DS1. Maddison and Megan feel similar.
But, if you like any of these, then that's where your taste lies, and you should absolutely use Paige, or whatever you love.
Incidentally, there were 3 Charlottes in DS1's year throughout primary school, yet it's still ftequently suggested on here.
I've always liked Harriet. I do know one of DS's age, but it doesn't feel as 'of it's time' as the others do, to me.
Peta/Elsa/Elise/Raine/Sadie?
I'm just trying to think of names with similar sounds to Paige.
If I were naming a baby girl, I would be considering Harriet, Adele/Adela, Eloise, Liza, Eliza/Elizabeth. What that says about my taste, I don't know!
Luckily, OP, you have plenty of time to enjoy deciding. Good luck
