Don't be scared. BLW is amazing! My daughter is 2 next month and she's had nothing but real foods since 6 months. She's never once choked! The only thing she chokes on is bath tub water which she for some reason loves to drink out of cups in the bath. We get so many compliments about how well she eats and how adventurous she is with food. It's been a wonderful experience and I'm so glad we did BLW. The reality is that they'll have to eat finger foods eventually, whether it's at 6 months or 8 months (which is the recommended time to start them anyway even if you do purees). They can't live on pureed food forever, so you'll have to go through the transition at some point, whether it's now or in a couple months. It's not easier or any less risk of choking if you wait (in fact, I would venture to guess it's more risk because babies have to re-learn how to eat, which is harder than just eating finger foods from the start).
As for the baby rice, yes, if you go down the BLW route, she shouldn't be spoonfed baby rice. There's really no reason to feed baby rice anyway as it really has no nutritional value. You can go straight to normal porridge or make porridge balls or fingers. If you really want to use baby rice, you can still make it up and give it to her in a bowl to feed herself. She can stick her hands in, scoop it into her mouth, lick her fingers, etc. This is a great way to offer yogurt as well and obviously works with normal porridge. From about 9 months, my daughter was able to hold a spoon that I loaded up for her. I started to give her porridge (just the regular kind) from then. I'd put it on the spoon and hand it to her and she'd feed herself. She was eating on her own with a spoon from around 13 months or so?
