I love Han/Leia (old EU version though), they're the OG SW couple. However, I also like Anakin/Padmé. I agree that some parts can be cringy but they're both on my favorite characters list, the development of the relationship and how it affects Anakin (also Padme) is great and Across the Stars is one of my favorite themes.
Edit: Another amazing couple is Luke/Mara btw. Perfect "enemies to lovers" thing.
