There is a very simple piece of knowledge you can apply to the situation; units with the lowest armour will always take the hits first, however, if something with higher armour takes RF from a unit in the opposing fleet, said opposing unit will target the ship with higher armour first.
Fire priority is: Random RF selection > Lowest to highest Armour value
Using this knowledge, you can in fact use the correct fodder for a fight to ensure you come out with the best possible result.
The example being presented here with the LF fodder with LG is because the RIP's will never attack the LG first round since their RF forces them to focus fire on the Light Fighters until they are dead, giving your heavies more time to bash the RIP's down.
A clever fleeter can correctly predict how fire priority is going to be executed and send the correct fodder for each fleet composition he/she is up against.
