I'm confused I Googled what fertilizer is required for onions and 1 search says onions don't want a lot of nitrogen and another search says onions are nitrogen hungry. ...so which is it?

All plants need some nitrogen. Now if you put a lot of N on the onions, you would have a big green plant above the onion bulb and probably little bulb. N produces leaf and plant structure. Generally if you prepare your soil with compost manures etc and let it all rot in over 6-8 weeks with watering and digging it over, and maybe add a little general fert in the process then you would not have to fert the onions again. A general fert is sufficient to grow most things - look up and learn about crop rotation also.
