The dynamic typing eventually makes certain kinds of bugs creep into your code and it can be difficult to realise.
Code written in dynamic languages are also more difficult and time consuming to refactor than code written in a statically typed language.
Dynamic typed languages always feels like I am 6 again, with my crayons all over the place, doing random bullshit go till something sensible comes out.
Good luck finding what is wrong if a bug occurs, good luck if you will refactor it and think how can you replace it, how can you rewrite it without destroying the whole aesthetic of the code. just like my parents trying to figure out how will they renew the wall after I draw a huge chunk of random shit to the wall with my crayons.
Outside of it, like utility packages, MongoDB or such so, you are not enforced, go with whatever you want.
...guess what my coworkers prefer! urgh.
