Several of the older trajectories for a manned mission to Mars included an inner system swing that included a flyby of Venus. While this is not an optimal trajectory in terms of travel time to Mars and there would be concerns about elevated radiation risk, it does raise the possibility of increasing the amount of data gained by including a close recon of Venus.
Specifically what kind of scientific data could be gained by a manned flyby of Venus by a manned Mars mission?

That was the short duration missions that required the longer return time..
Radiation from the sun as we approach we have not talked about for exposure.
We know of the cosmic exposures and what we might see on the surface of mars but thats a good question for the return.
While we are flying by venus why not set up some cube sat to monitor the atmosphere and send in some atmosphere grazers that come out of the other side rather than going to the depth of the surface.

I figured but couldn't an unmanned mission do that just as capably at Venus?

Of course the unmanned mission could and it would not need a flyby. We need much more data before men attempt to visit it clouds which may provide just the right amount of protection.
