I don't know exactly what you'd define as "wholesome" but here are some anime with minimal objectionable content and good old-fashioned values.
Shirokuma Cafe
Sougen no Ko Tenguri
Astro Boy 1960s (others are probably good too but I haven't seen them so I can't personally recommend)
Fireworks, Should We See It from the Side or the Bottom?
Wan Wan Chuushingura
Aria the Animation
Little Nemo Adventures in Slumberand
The Pretty Cure series
Tale of a Street Corner
Little Witch Academia
Most Ghibli (Shout out to From Up on Poppy Hill it's criminally underrated)
Ali Baba and the Forty Thieves
Heidi Girl of the Alps
Kemono Friends
Any anime about cute cats. Especially banana cats
Are you talking about The Devil is a Part-timer?
