Yes, slightly. But but don't think that you might experience a difference. The biggest advantage of nonwoven cloths is a better pressure strength along the fibre.
What makes a big difference is the fibre orientation. Do you need the stiffness in multiple directions, or just in one (or two perpendicular directions)? Because if you exchange a woven 0/90 layer with a 45/-45 biax cloth, you loose stiffness along 0° and 90° and gain stiffness along 45° and -45°. The difference gets smaller, the closer the layer is to the neutral fibre (usually the centre of your ply stack. This is why sandwich plates are almost as stiff and strong against bending.
If you need stiffness in just one direction, a  unidirectional cloth performs best

I need strength at 0/90 mostly, but I assumed there should be 0/90 non woven biaxial available right? If not, alternating layers of uni at 0 and 90 should be essentially the same right?

40 minutes is a very long time for such a "small" plate. Are you infusing along the shorter length? If so, your resin has to be medium viscosity. Like thin honey.

A plate of that size would take me about a minute.
