Start with these light Hammer Hunters: https://hammerbullets.com/product/264-cal-85g-hammer-hunter/
Load the above with enough fps to match the max distance you anticipate shooting at game. You will end up with about 8 lbs of recoil....then subtract the recoil reduction of the muzzle brake.....and you have a very tame deer slayer.
As the child grows and becomes accustomed to, and better able to handle, recoil; step the bullet up to the 97gr AH. Running over 3200fps with that 16" barrel should be possible. https://hammerbullets.com/product/264-cal-97g-absolute-hammer/
I have this exact rifle on its way to my FFL as I type this for my granddaughter who will be 7 in April. With a flat buttplate, it should be right at 12" LOP and a great platform for her to migrate to once she is ready to graduate from the 22 Cricket I got her.
