I think Ro came off as far more open minded about people. Because she traveled off-world in the diversity of starships and Starfleet academy, she was likely more accepting of interspecies relationships as Kira was, who only had four relationships in the entire series, only one of them being a non-Bajoran (aside from the initial attraction to Tom Riker and Chief O'Brien, which was just plain weird if you ask me.) Kira seemed always turned off by Dax's openness in her relationships and showed outright revulsion toward more diverse species like Ferengi and Captain Boday. Just my opinion, but that characterization of openness seems to have carried over in the continuing books concerning Ro.
And still, that's pure conjecture, and we never actually saw any evidence on screen of Ro's open-mindedness about people , or of her open-mindedness about inter-species relationships, except for her fling with Riker... which doesn't make her different from Kira. We're not aware of any other relationships she might have had... She did not have any relationships with Bajorans on Enterprise, but there were hardly any Bajorans on Enterprise, and I don't remember that we ever got to see any male ones. Kira, on the other hand, eventually had the weirdest of all interspecies relationships - is there really anything more unusual than a romantic relationship between a humanoid and a Changeling?

You really think that people who have travelled a lot or been in the company of more diverse people are by default more open minded? Not from my observation.
Also, I almost forgot to comment on this:
Basically the difference between Ro as First Officer vs Kira is that you would have one character who was not a spiritual Bajoran patriot and Kira who was very much so.
A
spiritual Bajoran patriot? That she wasn't. But a
Bajoran patriot? Very much so. She was all about talking about the Occupation, about her history on Bajor, getting angry at Picard for not using her surname first - the Bajoran way, insisting on wearing her earring... (That Trek costume people later didn't pay attention and had other Bajorans wear it on another ear, was just an insignificant error, and that Trek Lit authors later tried to give it a meaning, was pure retcon.)
I mean, come on - Ro is not Dax, she never came across as a particularly open-minded person, she is far more similar to Kira, and when she was introduced in TNG she was supposed to represent Bajorans. That she wasn't religious wasn't that important since Bajoran religion was very much a side issue on TNG.
