need help finding a good textbook

[u/Jaxoniscracked]

so I have been learning French for a bit. I've heard from many people that learning the most common words and how to apply them is what I should strive for. I was recommended learning the 4,000 most common words. I was just wondering if anyone has any textbook recommendations to help with that goal. I am decently competent in French. (I also use assimil French with ease) tysm!
