Fruits Basket: Okay, now this one is both rather violent and has a lot of cursing coming from one of the main male protagonists, however I advise you to overlook it in this case. Fruits Basket is probably my absolute favorite romance/slice of life anime, and the violence and cursing all come with good reason and traumatic pasts that the characters don't have too much control over. I have been in love with this series for around 7 years, and I still remember every episode because it is worth the time. I wasn't too big on cursing when I first watched the show, but the plot was entirely too amazing that overlooking it only seemed fair. Trust me this is an anime worth watching despite the violence and cursing. Now, the violence isn't too violent as it doesn't show a lot of gore, and the you only see one scene with a whole lot of blood. The only other scene with blood is just a tiny drop. And the violence isn't too bad- the kids just know martial arts, so it's not like they are out to kill one another.
But those are my suggestions, and I hoped they helped! I think violence and swearing are what keep more types of viewers interested so it'll be almost impossible to find many series without it, but with these series the violence is because those particular characters are trained in martial arts and are protecting something important to them. Very minimal bloodshed in these series, apart from the one episode in Fruits Basket, but we don't exactly see the impact that caused the blood so it should be okay! I really highly recommend these all, but my bias will always be towards Fruits Basket and Ouran High Schook Host Club the most. The others though are no slackers, and have more romantic potential than both Fruits Basket and Ouran because their relationships are further explored in their manga.
