Baby led weaning - resources?

I know this is probably common sense stuff but I always second guess myself on how to prepare food for my baby (7 mo). We did purées but I’m trying to introducing more solids. I know the finger length rule but what about pasta, rice and is shredded chicken okay? What about bananas, just cut them in half?

I follow feeding Little’s on IG and have googled some stuff but curious if anyone has tips?

Thanks!
