Does functional analysis help for stat phd admission?

[Lp_space]

I am planning on applying for statistics phd and next term I have the option to take measure theory and functional analysis. I heard these courses are especially helpful for phd coursework. However, I don't think the grades will be available when I applied. I also have the option to work as a biostatistician at a Pharma next term and I am not sure if this experience is going to boost my application. Just for the purpose of admission, which way do you think will I be better off?

Measure theory will be more essential, but any type of analysis will help you if you want to do theoretical research.  The exact subjects you will need to learn will depend on your research area.  As an international applicant, I would recommend taking as much math as possible if you can get As.  That will help you more than a non-research internship.
