the fuel produces has higher ignition temperature and produces more heat
It really depends on what you are using the fuel for. If you want a liquid fuel that easily vaporizes in a carburetor to make an explosive mixture with air and burns quickly to release a lot of energy, then petrol is better than wax. I you want a less dangerous fuel for a candle, one that melts and vaporizes to burn slowly in air, then wax is what you want. The reason for the different burning properties of petrol and wax lies mainly in the size of their molecules and how the carbon and hydrogen atoms in them are joined together.

No, it is not better it is just another type fuel.
Yes
In petrol, the combustion of hydrocarbons present is complete and they burn with blue flame. However, in kerosene, the combustion is not complete. It burns with smoky flame accompanied by the release of unburnt carbon atoms. Therefore, petrol is regarded as a better fuel than kerosene.
Yes
petrol is a hydrocarbon fuel
It's not a question of 'better' - they have different uses and purposes.
Yes, wax candles are a fuel.
No Petrol is a fossil fuel
petrol is made from the fossil fuel oil
Yes, you can use a fuel injector in a petrol engine.
