Do you know any Spanish or French series on YouTube? Or on Netflix? Or Youtuber who clearly speak the languages?
Netflix: House of Money, Elité
What is your previous knowledge?
You will not understand anything in "normal" series on Nextflix as a beginner.
I'm not a beginner
But you ask for "clearly speaking the language". How long have you been learning the languages? At school?
If in doubt, just try it. There are almost all series with Spanish soundtrack.
I've been learning the language for 4 years but think that most of the French people speak abnormally unclear and fast
This is normal for both French and Spaniards. And if you're not comfortable with it, it's because you still have problems with the languages. (That's not meant to be bad, but I see right now that you seem to be still a student.)
Netflix: House of Money, Elite, the telephone operators, Vis a Vis, Parallel Worlds. Everything is Spanish.
