The public TV normally has a homepage with news, documentaries, series and movies on demand for free (at least in the EU, use VPN or proxie if country restricted content) eg.RTVE in Spain or ARD/ZDF in Germany, same in Pluto TV which is free also a lot of free content in Rakuten TV. For music there is Bandcamp, https://www.internet-radio.com/, Pixabay (yes, it has also music, above free downloadable (all CC license) or also the FMA. Odysee also is growing a lot in last years with content creators which have emigrated from YT. Search content in your search engine, not in YT.

Certainly if you are looking for cat videos, clickbait shorts or AI slope, then there are really no alternatives to YT.
