Anime for my bedridden 78 yo neighbour?

Hi, everyone! I have a 78 year old neighbour whom I help with daily chores because she is bedridden for the time being. I introduced her to anime and she said it has been soooo good for her mental health and she has been watching 24/7 :P

She has watched Frieren (her favourite), Naruto, Demon Slayer and Solo Levelling.

She wants LONG animes that have adventure, travel, self improvement, underdogs success stories, etc. I think she only wants long animes because she wants to feel she will stick around, and self improving and adventure genre because it motivates her to do her physiotherapy exercises...

I would love to give her a list of animes like these but I don't really know that many. I usually watch short slice of life animes and I'm not that much into battles.

This is very important for her (and for me). I would really really appreciate recommendations and links.

I'm getting her a Crunchyroll subscription today and will add all fitting recommendations to her favourite list.

Thank you so much in advance!
