Rolled with the Sigma 30mm with my A6000 and I enjoyed it, but I was hoping for something with better bokeh, something that also has better color vibrancy that isn't a zoom. I also own the 210mm and I enjoy it, but I need a portrait lens that is a bit smaller than that. Any advice is greatly appreciated.
I think you acted totally too soon, too rash by rejecting this lens. This outcome is completely due to you not understanding how to achieve bokeh and ultimately it is an operator error.
As your name here says, please do get get too angry too soon, but instead try to learn and read up for example on 45 degree 'normal' angle lenses which are often not good for deep bokeh, you need a longer lens to start with. But that eluded you and it became your loss to learn. sorry. Just look at the Touit images: portraits with a standard angle lens are possible and have their own allure. And can be beautiful to boot! Your rash loss then.
