Physically, since it will be heavier with more rim and tire mass it will increase rotational force needed to turn the wheel and technically that would rob top speed as well as acceleration just like you brought up. Adding meaty tires is usually accompanied with suspension (or/and power) upgrades to give the car a set up to decrease the disadvantage of rotational mass as much as possible. Wider tires keep the vehicle more steady in the corners with more contact surface to the road and the usually accompanied suspension upgrade will cooperate and aid the beefy tires to stick its bigger contact surface to the road as well. Aerodynamical downforce modifications/upgrades are also a good combination with wider wheels. So as far as running stock with wider tires goes, physically I cannot see any pefromance beeing gained.
Hope I helped answer your question, apart from perfomance wider tires make our cars look like proper racers, gives an aggresive appearance. Cheers and good luck with your wheel searching!
