Hey Nestor! Well, depends mostly on your interests, of course. But you asked for a recommendation, so here's mine. https://www.youtube.com/watch?v=0x2_kWRB8-A It's a TED talk from a polyglot and avid learner called Benny Lewis, with years of experience in languages. Here's his blog https://www.fluentin3months.com/. Best luck, from one latin to another ;)

Hey Nestor! It depends what kind of music you're into, but you might try Frank Turner (British) https://www.youtube.com/watch?v=H9fD04ymdF8 and Willy Mason (American) https://www.youtube.com/watch?v=hozXe9WAK4E&list=PLBA70A6613DDC9B6B. Two of my personal favourites :) You might enjoy this website too: https://lyricstraining.com/en Hope this helps!

Like Rob said, it depends on what kind of music and series you like! I think Khalid sings pretty clearly (American R&B artist), as does Gabrielle Aplin (chill acoustic singer, British). On youtube, Safiya Nygaard speaks in a very clear American accent (most of her videos are themed around trends and fashion). If you're interested in learning more about other languages, the creator of the channel LangFocus, Paul, speaks very clearly (I believe he's Canadian) and makes very informative videos!
