Do you guys know what the inputs for stuff like fall damage cancel and this thing where you backflip jump attack and get more height somehow(I don’t know the names)

For FDC, it's:

1. pull out your bow midair (you have to cancel a dive with b if you're diving)
2. press and hold L and afterwards press Y so the menu opens when you just started the attack
3. let L go and quickly open the shield menu with D-Pad left
4. Switch shields
5. let go of D-Pad left and quickly press R and then B

You can look it up in the discord channel - there is a spreadsheet with all glitches and how they work

Thank you
