In manga? The world is your oyster. Plenty of users on other sites make extensive lists. So pick some wholesome manga, like picrel, and see in what lists it pops up in.
In anime? I guess Sasaki to Miyano and Umibe no Etranger. Can't think of any other anime that don't turn into some drama. I've also seen live action have more choices if you wanna go for it, though it's still less choices than in manga.
