Convert video .mov to .mp4 and normalize audio

Anyone familiar with ffmpeg and ffmpeg-normalize?

I have this macro that has a script to convert from .mov to .mp4 and it works, even though I'm not familiar with ffmpeg. I got this from a website. A lot of different version shared weren't working, just this one was:

ffmpeg -I -c:v libx264 -c:a aac -vf format=yuv420p -movflags faststart output.mp4

I would like to convert AND normalize the audio to exactly -1dB.
Can it be done with only 1 script?
If not, would I be able to convert and then normalize, but when I normalize, it doesn't degrade the video?
