So I wanted to get started on PROS but there seem to be two download options. One saying download for v5 and one saying download for cortex. I do not know which one to download. Please help, thanks.
The “Cortex” is the older microcontroller as seen here:

The “V5” is the latest micro controller, often called the “brain” as seen here:

Either one can use PROS, but you need the proper version.
Also note that the PROS environment for the V5 is backwards-compatible with the Cortex and is being actively developed, so I’d recommend downloading it anyway
