PED::SET_PED_SHOOT_RATE - void SET_PED_SHOOT_RATE(Ped ped, int shootRate) / shootRate 0-1000

PED::SET_PED_COMBAT_RANGE - void SET_PED_COMBAT_RANGE(Ped ped, int p1) / Only the values 0, 1 and 2 occur in the decompiled scripts. Most likely refers directly to the values also described as AttackRange in combatbehaviour.meta:
0: CR_Near
1: CR_Medium
2: CR_Far

PED::SET_DRIVER_AGGRESSIVENESS - void SET_DRIVER_AGGRESSIVENESS(Ped driver, float aggressiveness) / range 0.0f - 1.0f
PED::SET_DRIVER_ABILITY - void SET_DRIVER_ABILITY(Ped driver, float ability) / The function specifically verifies the value is equal to, or less than 1.0f. If it is greater than 1.0f, the function does nothing at all.

PED::GET_PED_ACCURACY - int GET_PED_ACCURACY(Ped ped)

PED::SET_PED_COMBAT_ATTRIBUTES - void SET_PED_COMBAT_ATTRIBUTES(Ped ped, int attributeIndex, BOOL enabled)

These combat attributes seem to be the same as the BehaviourFlags from combatbehaviour.meta.
So far, these are the equivalents found:
enum CombatAttributes
{
BF_CanUseCover = 0,
BF_CanUseVehicles = 1,
BF_CanDoDrivebys = 2,
BF_CanLeaveVehicle = 3,
BF_CanFightArmedPedsWhenNotArmed = 5,
