Foods an 11 month old can eat who can’t crawl, walk, or sit up on their own yet can eat?

I’ve been trying more and more here lately but since she still doesn’t have too much ability to move around and use her muscles often she gags so much on stuff. It worries the crap out of me! I think she’s going to actually choke and that’s my worst fear! Can you give me suggestions to start moving more and more out of purées? She eats stuff like mashed potatoes, mashed up banana and avocado. Things like that. Tried soft rice and soft French fries and she gags. Btw, she’s already in physical therapy to help and we’re trying to get her to weight bare more since she refuses.

I should edit to say she can sit in an upright position by herself she just can’t go from laying down to sitting up by herself. She has a virtual OT therapist also but it doesn’t seem to help.
