Prioritize grades over side projects ?

I completed a bachelors with honours in Quant Finance & Analytics, and i'm now completing a Msc. in Comp Sci. I have four internships, two as a data scientist, and I want to know what would be most beneficial to my candidature.
A) Keep my GPA of 4/4 for the Comp Sci Master's, to prove that I'm solid even though it wasn't the field of my original bachelors
B) Create a side project where I deploy a model using Docker and Streamlit, but relax on the GPA.
I already have another side project that I host on github, but the second one's objective (B) would be to be deployed. What do you guys think will be most beneficial for an employer looking at my profile for a data scientist role? All suggestions are greatly appreciated.
