Fractions with characters that don't have descenders or ascenders
The default vertical spacing for fractions accommodates the possibility of a character with a descender or an ascender (or the possibility of subscripts/superscripts). This is, for the most part, the desirable functionality. For example, in the code below,
$$frac{g}{a}=frac{a}{c}=frac{a}{b}$$
nothing needs to be changed. However, there is occasion where an expression like the ones below
$$frac{a}{c}$$
$$frac{a}{b}$$
$$frac{b}{a}$$
occurs in isolation where a reduction in the vertical space on either side, or both, seems warranted to balance the fraction.
If I'm going on a final pass through a document, what would be the best approach to remove this vertical space that would be compatible with a change of font?

Apart from don't: you write your own macro that typesets numerator and denominator inside boxes and measures it, then draw your own version of a fraction that only uses those sizes and nostrutor similar.

I'm not sure it's a good idea. Anyhow, here's an implementation that should only be used in displays (fractions in text style or lower are already adjusted).
documentclass{article}
usepackage{amsmath}
newcommand{afrac}[2]{%
dfrac{adjustbot{#1}}
{adjusttop{#2}}%
}
makeatletter
newcommand{adjustbot}[1]{%
begingroup
settodepthdimen@{$textstyle y$}%
raisebox{dimexprdepth-dimen@}{$m@thtextstyle#1$}%
endgroup
}
newcommand{adjusttop}[1]{%
begingroup
settoheightdimen@{$textstyle l$}%
raisebox{dimexprdimen@-height}{$m@thtextstyle#1$}%
endgroup
}
makeatother
begin{document}
[
frac{a}{b}afrac{a}{b}quad
frac{a}{c}afrac{a}{c}quad
frac{b}{a}afrac{b}{a}quad
frac{g}{a}afrac{g}{a}
