Mikayuu isn't canon, but Mika being in love with Yu is! The reason why so many people have automatically jumped to "Mikayuu canon" is because the fact that Kagami actually outright said that Mika is in love with Yu is a really big deal. It is next to impossible to find a non-het pairing in shonen (in fact, I can't even think of any?), so having Mika say "I love you" to Yu is a momentuous thing. People enjoy having representation!

I'm not going to comment on which pairing is "more likely", because this is an post apocalyptic world full of death and misery and the story is more than just ships. I'm not that big on shipping, so if they all make it to the end, I'll count that as a win.

tldr; Mika being canonically in love with Yu is a really big thing and although it can be taken too far, it's still important to let people have fun with their own ships! This isn't a happy series, and if any of them end up in relationships by the end I'll be surprised.
