A few late thoughts on your update. I love the handwritten feel of #2 but there's just something about it that feels off. #5 feels a bit too formal and I actually prefer the heavier S on #2 now that I can compare.
I went looking for some typefaces for the "ea" that capture the feel I like. The shape of the S is perfect. Obviously you may not own these fonts, but they might help for reference. I made myself a rough mockup and both of these really felt right, so if you want to see it let me know. But I hate when my clients make mockups for me, so I will let you run the show! :)
