The best Van for Delivery man is Yankee as it can carry all items at once (50 capacity)
Also Sanchez is best for Firefighter, you haven't even mentioned it
You are bound to have a Fire Truck if you are doing the fire fighter side mission of extinguishing cars.
You said that DFT has bad acceleration which is false, it has insane acceleration for which it is the best.
Now, you don't even need a boat for fisherman. So a cheap "Dinghy" is the best.
An ambulance is far better than the uncontrollable Medic Car
