What would I have to replace to get my iPhone working again?

So this first part is shameful, but someone threw my iPhone quite hard at a chair that had a thin raised band at the back. It hit that band. The case flew off and when I picked up the phone, it was bent in the middle and would not turn on. I have tried leaving it on the charger all night, safe mode, force reset, plugging it in to my computer ect. The screen isn't broken or anything, the only physical damage is a slight bend, much like you'd get from the bendgate fiasco. Do you guys think some parts got moved around inside from the impact? What's the most likely thing I'd need to replace? The majority of the impact was a third up from the bottom on the left side of the back if that makes sense. If I can't fix it is their a way to get the sd card out and recover my photos? I REALLY don't want to lose my photos. Finally, should I bring it in to apple? Or will they just give me that 323$ replacement thing. Because if I get a replacement I want more than 16 gb storage, that was killing me. Would they allow you to upgrade that for a bigger fee? Do you think it could possible fall under warranty if I lie and say it bent by itself (I am very poor and Apple is a multi billion dollar corporation). Anyways, thank you so much for answering any and all questions.
