My favorite slice of life is Natsume Yuujinchou aka Natsume's book of friends. Deeply heartfelt, nostalgic and major Ghibli vibes. The anime follows the series exactly which is amazing!
Fukigen Na Mononokean (same vibes as Natsume)
Lord of The Mysteries (can't recommend enough!! Read the webnovel it's a masterpiece! The series got re-worked into stunning gothic art and the anime is highly rated too but they're both rushed and book is simply better!)
Papa Wolf and the Puppy (really healing)
Atama no Ue sadly hasn't updated which is strange considering the boom after the animation
My Dead Husband Won't Stop Bugging Me ... you're gonna ugly cry and it's beautiful
Rec - Kimi Ga Naita Hi (another ugly cry and it's a sad ending)
Bizarre restaurant (much more light-headed)
Hunter World's Gardener
There's more but I can't remember them rn. Hope this helps!
Between this and Hello! Veterinarian! my eyes are forever moist ( ╥﹏╥)
...but I love the pain ig
