I'm going to struggle to put my feelings about the ending into words but Ill give it a go.
I felt like it was trying to be over clever. Instead of giving you the 'happy' ending of them spending their eternity together or the 'sad' ending of her wanting to be with her family it felt like they were trying to go for an ending that left you questioning whether it was a happy or a sad ending and whether 'heaven' was a good thing or not. But in the end it just felt like it hit a bum note with me, failing to do anything it set out to and leaving me confused about the sudden change of heart with little explanation.
I think you are somewhat on the mark. But I don't see that as a negative.
The episode explains pretty well why Kelly would be against staying forever in SJ and why Yorkie would be so enamored with it. That Kelly monologue is very important in this context because it does not only speak for her past with her husband but also perhaps her future in SJ with Yorkie. The change of heart does not feel like a cop out for me since they devoted enough time to the core relationship to show that Kelly could conceivably want to spend more time with Yorkie.
Kelly's intentions on not connecting with anyone in SJ is a very important plot point. She is adamant on following through with way her husband and her daughter died but her determination to just have superficial fun in SJ speaks to her weakness of succumbing to the promise of ever lasting life with a loved one, even when she knows the negatives associated with the same.
