Turbavykas, my company has a massive amount of difference among our fleet, to the extent that we have 4 or 5 variations for each section of the FCOM. The best way to read through them is to select one MSN/Tail-Number and use that aircraft as the "Default" version so to speak. Study that aircraft alone, don't worry about the rest.
Ask your company which aircraft you will be doing your sim on, i.e. which type and variation the sim is setup to replicate and then study that aircraft exclusively. When you get to line training study the difference between that aircraft and the aircraft you are going to fly. There is little chance that you are going to be able to study all the variations at the beginning of training, so chose one and stick with it.
