Well I do have a matchmaking tag but I don’t usually see canon fics where they kids are getting them together. Usually it’s AUs where there’s matchmaking or someone like Logan.

I found a few in Ao3’s matchmaking tag that might be what you want though:

An Idiot’s Guide to Matchmaking by ourgirlfriday (G, 1k) - Hank McCoy was the first to admit that, for a certified super genius, he could be really, really stupid. But he knows that the Professor is lonely, and, well, it’s up to him, Alex, and Darwin to fix that. What’s the worst that could happen?

The 12(ish) days of Christmas by ourgirlfriday (4k, NR) - It’s the twelve days of Christmas, and the children have a plan.

Summary: Charles finds a letter Erik had not meant from him to read.

Rating: General

little-magnolie's thoughts: uuuuh, this is my first cherik-fic ever and I listened to a lot of soft music and I made an edit for it if that helps you its right here x3 I hope I did this correctly!

Summary: Magneto finds himself in 1962, on the morning they go to Cuba, in the bed of the young Charles who'd spent months letting him think they were in love before breaking his heart. But he is not the same man he was forty years earlier, and as he gets to know young Charles again, he discovers that things might not have been exactly the way he remembered them after all.

Rating: Mature

Warnings: Could be seen as dub-con or taking advantage since young Charles is unaware that he is not with his own time's Erik, Child abuse, violence against a child, self-loathing

I’ve never read any stories where Erik has a sister named Ruth. But I did a hunt on Ao3 and found the one below. Is that what you’re looking for?

In Time of Test - by Katbelle

Part 1 - Family of Blood

Time has the amazing ability to correct itself. Ruth Elisabeth Phillips was born someone else entirely, but no one knows that. And between rage and serenity, she's the middle ground.

Canon!AU centered on another Shaw survivor. How much would the world change if Ruth Lehnsherr survived the war.

Part 2 - The Art of Falling
