Somehow the original BLW philosophy has been perverted to be about the presentation of the food solid (BLW) vs liquid (puree) .
There is a taste acceptance window which is quite small and for this reason, food before one is anything but fun or unimportant, because it will shape a child's food preferences likely for life.
For this reason it is very important to present the widest variety of vegetables when they are accepted, to encourage the preference, and a gut and mouth microbiome that thrives on them.
Soups and purees or other smashed food, allow to massively increase the variety of vegetable offered. In soup, you can play around with taste, thickness and flavour by combining vegetable together. This is what cooking is about, the combination of flavours, which you can't exactly obtain when offering single softened veggies.
A carrot-pumpkin soup, a pea-potato soup, a minestrone, chicken soup, even fish soup...... will develop a taste not only for the single vegetable ingredient but also an openness to taste combinations.
In the end , what matters is not the form (liquid vs solid) or the way it reaches then mouth (spoon vs hand), but what the food is.
What will determine a fussy eater is the food the child is given. Give melty puffs, rice cakes, rusks as snacks, or even pouches with their weird combination and overly sweet tasting and the acceptance of food will be pushed towards industrial, packaged or processed food.
Weaning isn't a choice between solid or liquid. You would be missing on risottos, stews, couscous with veggeis and so many food that comes in different form. As adult we eat some foods with our hands, other with a spoon. I know people will be posting pictures of babies covered head to toes in asparagus risotto to prove that you can BLW yoghurt, soups (by sucking fingers) and so on. Weaning is also teaching "how " to eat, yes mess is fine, expected, food going many places minus the mouth, but sucking mum's fingers for soup (as we read here...)
Think "celery" , too hard for baby, disgusting boiled, but chop it, braise it in a pan with chopped carrots, chopped onion and after 5 min chopped tomatoes, let it sweat and mix with baby pasta, or a ladle of broth and couscous, you have a great dish.
Still celery, very hard to eat, but if cut in tiny stripes and then slices as thinly as possible, put in bowl, squeeze half an orange on top, extra virgin olive oil, fresh parsley . Leave aside for 30 min, it turns super soft and you can give it in its juice (half a spoon with plenty of sauce)
You might have slightly more vegetables to offer by just weaning without any label .
So my advice to you @Paris2019 is don't think about spoon/finger, but focus on the food. You don't have to pick, because as adult we eat in many forms. Start with the vegetable you want to give that day. Which form is best, softened , roasted to eat with hand/fork or with some form of liquid or grain hence the spoon.
