As a Practicing Catholic I'll give my first takes, because I think some people might be curious to hear our perspective (You might not be, but ah well)
Well, it's huge to see an Argentinian Pope, one of the Italian Cardinals (sorry I forget which one) had said earlier that they (The Conclave) need to look at our Brothers outside of Europe, particularly in Latin America.
Pope Francis I is likely not because of Francis of Assissi, but more likely Francis Xavier who was a great Jesuit and missionary.
Also, this is kind of surprising, this was the first time a new Pope recites the prayers with the people on his first appearance, Our Father, Haily Mary and Glory.
Another take was his refusal to wear the red cape (I don't remember the proper name right now, Sorry!) in contrast to both Benedict XVI and John Paul II, who both wore it. It looked like he just wanted to be very humble about this.
Thank you those of you who aren't exactly of my faith who are being respectful, haha even some of those jokes have made me laugh quite a bit. This is, quite a historic moment.
