Video background songs that are nostalgic & hopeful?

[laintpe]

I'm working on a promo video for a mental health walk and finding a song that is acoustic and isn't too peppy or too dark or only about romantic relationships isn't going so well. That, and the lyrics matter quite a bit given the topic. I thought of a song that had the right sound and tempo but forgot that "when all your friends are gone" is part of the chorus— definitely doesn't work.
Any suggestions/ideas?

This is an underrated atmospheric track used for Enslaved: Odyssey to the West's main menu and a personal favorite. It might have the hopeful yet pensive qualities you described.

It's not acoustic or a song structure with a chorus though, just ambience

Does it need to have lyrics?
