How do you call this style of music?

I really love this style of music but cannot search for it because I don't know what it is called. I think all of these belong to the same style I am looking for:

From a composition perspective, I guess the commonality is that there is an underlying motiff/arpeggio that keeps repeating rhythmically as the chord progression changes. Then there are long notes played in higher registers, usually strings, etc.

I searched for words like new age, chill, lofi, ambient, epic, etc. but have not come across anything similar to the links above. I even messaged the YouTube channel in question asking about the music, but no response. If anyone can help identify this style of music, or even give some artist recommendations, I would be very grateful. Thanks!
