Have you looked at the DYI option instead of the pre built one? Assembling this laptop is doable in 5 minutes for a 3 years old kid ;) You can even find step by step guides videos and that will bring the price down to your higher limit of 1000 euro. That may be a good option if you like the concept so much. I'm personaly looking to get one of those for my next machine.
Also, this discussion may help you. It's on the framework forum but comments are not only all positive which reflects liberty of speech. Another plus in my view. Finally, always remember to compare apples to apples and take longevity in consideration. Not all processors with similar specs are the same for example.
If you're looking for an in-browser alternative I'd highly recommend you take a look at the LibRedirect extension for Firefox and Chromium. It'll automatically redirect any youtube URL to your preferred alternative between Invidious, Piped, PokeTube, CloudTube, Tubo, FreeTube, or Yattee.
If you're looking for an external app and like using your terminal then ytfzf may be a good choice. I've briefly talked about it here. It will even allow you to search on Youtube (through invidious), Peertube, and Odysee if you so desire.
