IF you can find them. Also you have no idea about quality. I've watched several videos in my TL where the plot was 1 here is what I'm going to do, then 10 minutes silently doing it, then 1 minute of reflection. There are a lot of videos of one guy doing something without talking. Note that the above is probably a reflection on my tastes.
I've also watched several videos and concluded after a while that it wasn't my TL but a related language.
Best way to start is watching tv news. Hosts have very clear pronuntiation, it's their job after all.
I first research what tv channels are more popular in the country, then search YouTube with that info. YouTube doesn't seem to offer a lot of search options, but it's possible to do the search from Google or DuckDuckGo and later select "videos" tab.
DuckDuckGo has a dropdown menu that allows search localization, so the first results are the most relevant to the selected country. Once you find a handful of interesting channels, you're set up.
The only thing I disagree with is best. Best is subjective, I find most news boring an irrelevant (a lot of gossip about people I don't care about) so while it is great if you can stand it, I tend to get mad about the subjects they consider worth covering and turn it off.
This is a reflection on me of course - you should have your own opinions.
OK, let's say that it's a good way to learn the language, not so much as entertainment. Actually I agree with you about how little of what we see in the news is worth covering.
Anyway, if there's a channel with lots of contents, it's still possible to select only interesting topics. Maybe it's easier for me, because the language I'm most interested in is English :) Usually I don't even need YouTube, just setting Netflix language to English.
For other languages, I'm mostly interested in listening to specific words pronuntiation, usually names.
