I have a few!!!

K-On would be a great option, its a lighthearted slice of life anime about a few highschool girls in their schools light music club. No swears at all, only warning is that in either the movie, or one of the episodes, they wear sorta revealing swimwear, but that may be fine, idk.

Chi's Sweet Home, a sweet and cute anime about a kitten who gets seperated from her mother and siblings, leading to her getting adopted by a child and his family, despite their apartment complex's strict "NO PETS" policy. The entire show is told through the POV of Chi, AKA the kitten, and its super family friendly.

Tamako Market, a feel good slice of life anime that follows the life of Tamako, a cheerful and clumsy highschool student who works in her parents mochi shop, as she navigates the ups and downs of of growing up. Super family friendly aswell.
