Been "almost" 5 years, should I already apply for citizenship given the waiting times? (I might be eligible for applying after 3 years)

Hi everyone,

hope you are having a nice Monday without the stress of any German bureaucracy. I would have a quick question and it is basically the title...

I been living and working here for almost 5 years in Öffentlicher Dienst on a high-skilled role and before that I got a Master's from a German Uni. On the side, I work as a coach for two sport clubs, which is underpaid and some sort of charity work. I don't have any C1 certificate, but I would probably manage it, if need be.

Do you think should I apply given the waiting times and the possibility that I am already well-integrated?
