Nice tank and nice lights! I bet it will work well.
I have a 125g, same length as your tank, with 2 Finnex Planted+ 36 inch lights, end to end to span the 6 feet. I am very happy with them (photo below). I consider mine equivalent to what you got. Nice.
I do believe that in your tank, which is wider, in time (such as when the plants start to populate heavily) I would feel a need to add a third, 24 or 36" light, by the middle-back of the tank, which would produce an attractive two-tone effect, with a central brighter central part, and less bright regions on the sides. Enjoy!

Looking great so far. What’s gonna be the total stock in the tank?
You won't get intense reds but none of the plants you are growing are so should not be an issue. I would recommend some crypt parva because it is a short plant and a bright green for when the dwarf sag bolts to 18in or longer.Amazon sword, jungle val, bacopa, bronze crypt wendtii, anubias nana and dwarf sagg. I chose easy care/low light plants simply because this is my first planted tank. I’m really hoping the (2) 36” fluval plant lights produce enough light. The guy at my lfs kind of made it seem like it wouldn’t be but I somehow doubt that. I have them on for 10 hours right now.
