I'm considering a Necky Manitou (12'10") for light weight, seat, looks

Mainstream Biscayne (14'6")?

Impossible to say. There are many factors that affect speed and overall
length isn't one of them.

I won't be going all out though, just keeping a medium pace for workout.

If all you want is a workout, it doesn't matter how fast the kayak is.
One hour of paddling is one hour of paddling regardless of what you
paddle.
