If you're not certain what you want, try a few clip ons, available, inexpensive. They work very well, and you can try a lot of different colors, shading, gradients, and polarized. I especially like the flip-ups, quick change capacity. I prefer a medium brown, polarized- gives a little better vis in precip.
You may have issues with helmet visors (diffraction color bands, distracting), the occasional plastic windows (twice in 20 years), and gauge face glass. The biggest issue is LCD displays- polarized lenses will conflict with the LCD polarization at some point, or all the time. I carry an extra pair of cheapo non-polarized clip ons.
And a pair of collectible frame RayBans with scrip lenses, when I gotta look like Joe Cool, pro pilot. But not to work in.
