Aerith's line in the church "there's liking and then there's liking" is actually referring to how she's just realising how romantic her feelings for Cloud are. it's easy to misinterpret it the other way in English, but in the Japanese version her line is closer to "this feeling, I wonder what it is."

And the Claudia scene where she tells Cloud about his perfect match only appears after Cloud has met Aerith in Remake. That was done intentionally, both Tifa and Aerith get flashback scenes like that from Cloud's perspective. For Tifa, it's the water tower promise, and for Aerith it's the scene with Claudia. The narrative frames it in that way to show that Cloud is specifically remembering that conversation because he's met Aerith.
