$selected_fonts = array(
    $body_font['face'],
    $heading_font['face'],
    $menu_nav_font['face'],
);

One or more of these variables is a string, which you are trying to access like an array, this only works if you access it with a numeric key slammer than strlen-1

To confirm this, do a var_dump($body_font, $heading_font, $menu_nav_font) too check which one is not actually an array, but a string.

well, then my assumption was correct, and you have an illegal offset because you are trying to access a string as if it were an array

Try:

$selected_fonts = array(
    $body_font,
    $heading_font,
    $menu_nav_font,
);

As $body_font, $heading_font and $menu_nav_font are string, using those as array will produce the warnings.

EDIT:

To be more generic:

$selected_fonts = array(
    is_array($body_font) && isset($body_font['face']) ? $body_font['face'] : $body_font,
    is_array($heading_font) && isset($heading_font['face']) ? $heading_font['face'] : $heading_font,
    is_array($menu_nav_font) && isset($menu_nav_font['face']) ? $menu_nav_font['face'] : $menu_nav_font,
);
