You can get the value of Beaver Theme customizer settings values with FLTheme::get_setting which is similar to the get_theme_mod function, it works like so.
FLTheme::get_setting( 'fl-body-font-family' );
So in the above, the font value is got from the Customizer > General > Text > Font Family
Assign it to a variable and var_dump it out to see it.
$font = FLTheme::get_setting( 'fl-body-font-family' ); var_dump ($font);
Now you will see the value
string(11) "Avenir Book"
