Not an expert at all in fried rice making, but I'd say I have eaten enough of it to know what is good and what is not.
In general, regardless of how you cook your rice, it needs to have less water content than white or brown rice in asian food. Some people like to make fresh batch with like 1:0.9 rice to water ratio to keep it dryer, others just use normal 1:1 ratio then refrigerate it overnight. Some people like to use long grain rice like jasmin, others like to use short grain rice like Japanese or medium grain. There's even the sticky rice version of it for winter solstice, so whatever you like best (I'm a Jasmin fried rice kind of person).
Ingredients should be dry, and precooked (except for eggs, some would mix in later but some would fry them first as well) so it doesn't release water, and cool down the rice while you cook. The techniques all require you to sear the rice so it caramelize the rice to release the aroma (aka wok hei). You can use a frying pan or cast iron pan, or a wok, but don't over crowd it and make sure you sear but not burn the rice. Only after you get it to smell like fried plain rice then you add your other ingredients, and if you prefer to add eggs last, add them last.
Some use butter (hibachi), some don't, some use soy sauce, some don't, you have to see what you like to add and just do your thing.
You don't need a lot of oil, for a skilled chef probably 2 tbsp only for a whole plate of it. It shouldn't be wet with oil when it is done and the frying pan / wok should just be glossy instead of full of oil.
