Unfortunately, the "right" rod is usually the one your most comfortable with casting, and we can all cast the same rod, and have different opinions about it.
I also have no experience with that Orvis rod, but if you can get it at a decent price, it would be worth at least trying it out! That's not some cheap no name fly rod, made in China!
But, I certainly agree with ddombos2, an 8 wt should be a fine choice for a general purpose rod for the species you've mentioned! As far as actions being fast or moderately fast, you can cast two different rods from different makers that use these designations & sometimes find there's little difference. There's no real standard, and the only true way to tell is to use the rod.
Good luck with your search!
