The science (unless paid by the person who invented this BLW concept) is not in favour of BLW :
"“The evidence so far on BLW is not all positive. “There are also concerns as to whether all babies are developmentally ready for grabbing chunks of food at six months. Professor Charlotte Wright, a pediatrician from Glasgow, found that, of a sample of six hundred families, only 40 percent of babies were in fact ready to self-feed at six months. By eight months, 90 percent were ready to reach out spontaneously for food. This indicated to Wright that it was “unrealistic” to expect children to rely exclusively on self-feeding when they started on their first tastes of solids. ”

Only on MN, is there this battle between spoon and finger, just focus on the food, not the mean by which it reaches the mouth.
Ignore the ideology battle, and grab the unique opportunity to offer fresh food, give her a variety of vegetables, focussing on taste.

Think about how you eat and offer food you usually eat with a fork/spoon in the form of purees, soups, stew with cutlery and food you eat with your fingers, without once she knows how to swallow.
Explore the world of tasty vegetables, rich creamy soups, risottos, and once she knows how to chew and therefor how to produce saliva to help food go down, you can widen the food and even offer small bites crushed with the back the back of a fork from your plate (as long as low ion salt) because this is another big BLW failing. It makes only sense if the family has a healthy diet, not if high in processed food, take aways, ...
":“But in one small study of American mothers using BLW, it was found that the grown-ups—and by implication the babies—were eating excessive amounts of sugar and salt and inadequate amounts of micronutrients, especially folate.”
Ignore the trends @Autumn13 and think about the WHAT you would like your child to eat, not the HOW. You want her to develop a preference for vegetables and not processed. Easy, don't ever give her processed food, such as the puffy snacks, sugary snacks bars.
A child will like the food they are used to. Some tribes have terrible food (according to our Western taste) but to their children it is the best ever.
