There's no such thing as "instant energy" when it comes to food.
What you may be referring to is an energy boost, which is a quick spike in blood sugar with little to no burden on your digestive system.
Eating 500kcal worth of steak would make you feel sleepy, while eating 500kcal of watermelon would not.
If the blood is not redirected to the digestive system for extended periods of time, we experience less of the sensation of being tired upon a meal.
It's the reason, after a big feast, all you want to do is lay down and die.
But, you eat a small snack before hitting the gym.
Hence, generally, for snacking you should choose fruits which take the least effort to digest.
However, it is important to remember, that in case of fruits, we are not dealing with "normal" sugar.
Most juicy, sweet fruits are rich in fructose rather than glucose.
Glucose being the primary fuel of all human cells.
Fructose need to be converted into glucose before can be utilized by the human body.
Which happens in the liver.
That extra step is the reason why, even if you didn't know it, you need to avoid corn syrup in your diet.
Because the liver need to convert extra sugar, it will not be available for the rest of the body, and usually will be converted into fatty acids, and stored away instead.
Now, this is not a kin to saying "don't eat fruits, you'll get fat".
It's a kin to say "don't look for energy boosters, eat regularly but in small portions"
Blood Sugar boosting wise, there's virtually no difference between eating a banana and eating bread.
But if you must choose.
Eat Banana, Kiwi, Apple, and Pomelo.
The best fruit one should it if he is looking to get an energy boost is definitely banana!
Because it is packed full of important nutrients, fibers, natural sugar, vitamins, carbohydrates, potassium, vitamin B6, and essential amino acid tyrosine.
Energy boosting benefits of eating bananas include:
That's why you will often see athletes, especially tennis players, eat a banana before and during the match to keep their body fueled, boost their energy levels and improe both their performance and endurance.

The best fruits for energy are the most calorie dense.
Also there is no such thing as instant energy.
Bananas and dates are a good choice. Dates are fantastic due to their small size and decent calorie density for fruit. Grapes are also another good choice.
There is a reason why bananas are so popular at professional sporting events. If you go to any event where there is time to eat you will find the pro's eating bananas. When people must eat on the go like with ultra marathons they may prefer dates or gels, again because of the size and calories offered.
The reason I also like grapes is because they are also really hydrating.
