On accessing Youtube: I’ve been using FreeTube for years and it’s great, it even has support for Sponsorblock, and your subscriptions are stored offline in the app, among other benefits. For the browser, there is also the Libredirect extension, which you can use to easily redirect to Piped or Invidious instances.
