I find it a little glaring that they specifically mentioned that Just Friends is Star and Marco's #2 favorite song. I interpreted it as there might be some other love song that is their #1 song that the writing staff want to reveal later once Starco actually goes into full gear.
Meanwhile, Jackie's favorite song IS Just Friends, which is a stark contrast to previously mentioned. It could be foreshadowing that Jackie would be okay with being Just Friends with Marco eventually, which fits her personality.
The way I see Starco and Jarco is that if Star and Marco would be together right now, there would not be that much personal growth for the two characters, as they seem to be fine with who they are. Jackie and Marco however, it seems like Jackie has more to offer to Marco than vice versa as Marco still has a self-esteem issue that he needs to get over. She seems like basket-cases that she can use her abilities to help fix.
Star also needs to mature and learn to take responsibility in order to deal with everything that comes with being a teenager.
It would make sense for the writers to reward the viewers with Starco once the main characters develop, since at that point they would be comfortable with their feelings.
But how would they make sure Jackie isn't left out? Give her another person to fix. Who needs the most help? Tom.
