if you're being shadow banned then YT has the same potential for reach than Flare, ZapStream, Odysee or any other platform out there. I don't think it matters where you host your videos. What matters is how do people find them and for that you already have your nostr reach and your followers on other social media network.
People interested in your content will find it through your socials and they wont care where it's being hosted.
