For a YouTube replacement, maybe look into Nebula, it's a subscription streaming service, but owned by the content creators, no ads. It also has some podcasts.
Regarding music, I listen mostly to somaFM. It's an Internet radio with lots of different stations. Mostly independent artists. It's free, no subscription, no ads, listener supported (you can donate/buy merch to support them).
It's really great on the Stream Deck. The controls work perfectly. I played it a lot while commuting.
