I personally would select "dB" in Preferences, because I find it
generally more useful.
(Is a noise floor of 0.00082 OK?)

I'd imagine that our aspiring audiobook producers would also prefer dB.

No I wouldn't change the meters to -6 dB as the half way point.

Do you think it's 'not' confusing to have "-30" as the half way point
in the meter and "+/- 0.5" as the half way point in the waveform?
Is it 'not' confusing to have 0 dB when the waveform reaches "1"?
Is it 'not' confusing to generate noise at 0.8 then amplify by 1.938
dB to bring it full track height?

Meter type: Linear or Logarithmic

Whether the numbers are +/- 1.0, dB, %, 0 to 127, -32768 to 32767, or
whatever, would be a "Preference" setting.
I think we would only want +/- 1.0 or dB, but other options are possible.

Track type: Waveform or Waveform (log)

Labelling of the vertical axis according to the user's preference setting.
