When you say "Normalize" most people take it to mean make the maximal level a certain value. Your waveforms can still look very uneven if one of them has a more constant loudness and the other spikes up occasionally. The peaks will be even, but an audio clip that has only a couple of peaks (or maybe just one) will appear lower overall -- and in fact will be lower overall.
If you mean "restrict the audio to be between -6 to -9 dB" that is entirely different, and isn't what most readers will understand you to be asking.
As I mentioned, Fairlight has a Compressor and you should use it just as you suggested that you would use it in Final Cut (I think that's what you mentioned). A compressor can make your waveforms look more alike -- though it may also make some of them sound quite unnatural, and can boost the apparent level of noise in a quiet clip.
Jim pointed out that trying to "normalize" -- i.e. just set the peak -- isn't a good goal, which is what you are also saying, I think. You want to work on the overall loudness level, not just the peaks. Again, you will either use volume keyframes on a section-by-section basis -- which you've ruled out due to the large amount of audio -- or you'll use the Compressor. There are specialized plugins that can be bought that will essentially adjust volume levels on a section-by-section basis if you feel you need that.
Fairlight has a nice LUFS meter where you can see True Peak and you can see Integrated LUFS and from what I understand the goal is to have the True Peak not exceed some level (say -1) and to also have the Integrated LUFS near a target. (In the case of Youtube, 14 LUFS I believe.)
