Yes, they will fit.
I haven't done it (my car came with 20" wheels) but it has been confirmed many times that OEM F-Type 19" wheels fit over the front 380 mm brake calipers no worries. The stock brake and wheel spec for the F-Type V6S up until very recently has been 380 mm front brakes, 326 mm rear brakes (called "High Performance" brakes) and 19" wheels, so they are a factory fit.
Just make sure they are factory OEM F-Type 19" wheels as very few other 19" wheels (including other Jag wheels) will fit.
The V8S came stock with the "Super Performance" brakes, 380 mm front and 376 mm rear.
