Swede here, at school I learned both English and Spanish, I consider myself to be Swedish/English bilingual, but even after six years of proper in-school Spanish classes I have only a brief surface level knowledge of the language, it is about 20 years since I last took classes in Spanish, and I never used it outside of class.
My English however, I have used that daily for the last 20+ years, both at work and at home, over the years I have learned common expressions and slang, and have been told several times that I speak excellent English.
My point is that I would recommend prioritizing learning one or at most two languages outside of your native language, but learning them well, rather than trying to cram in as many languages as possible.
One thing that has served me well however, is understanding pronunciation of foreign names, pronouncing other people’s names properly when other’s wont bother to will grant you a lot of respect and help you work together.
