For future readers, which will probably be me again 6 months from now, all I needed was to create a QStyledItemDelegate with paint() reimplemented as follows:

void customStyledItemDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QStyleOptionViewItem subop(option);
    subop.state &= ~(QStyle::State_Selected);
    QStyledItemDelegate::paint(painter, subop, index);
}

Then when an item is selected, it just gets painted the same as the model's Background and Foreground roles was already telling it to.
