I asked the same question last year. The one that is frequently recommended is Engrenages(also called Spiral)
That show is worth watching even if you are not learning French.
Scène de ménage is pretty fun, Golden moustache is a YouTube channel that makes really fun stuff, they even have English subtitles.
A few films are also worth watching: les visiteurs and intouchable. I can't think of anything else now.
Scènes de ménages, very funny, lots of slang and real-life usage.
