The main difference is that Team and Individual Day is a traditional, standardized process meant simply to document who is on the roster for yearbooks or leagues. In contrast, Media Day Media Day is an immersive, high-energy marketing event focused on capturing cinematic, personality-driven content for social media, hype videos, and promotional banners.

A lot of people start with umbrellas. They produce beautiful soft wraparound light just like a softbox would but instead of being more controlled the light bounce around the umbrella to diffuse first and then sort of scatters in all directions.

The softbox produces soft light as well but contains the light inside and only releases it through the diffusion panel in the front.  Meaning that the angle of light is more narrow than that of an umbrella when placed to the side of your subject you can see how the background is much darker and deeper. That's because the edge of the box keeps the light moving in a forward Direction. 

Whereas when the umbrella is at the same angle it can illuminate your subject and more of your background because of the wide open nature of its shape it all comes down to controlling your light. 

The more you know the more you can do.
