I don't think it's that easy, since Apex is not scaling the 360° distance using angles like CS:GO. This won't replicate anything.
With your settings, when you zoom, your zoom sensitivity is faster than the hipfire sensitivity by a factor of:
SG 553 / AUG = 1.07433...
Zoomed 1: AWP, SSG 08, G3SG1, SCAR-20 = 1.08678...
Zoomed 2: SSG 08, G3SG1, SCAR-20 = 1.12670...
Zoomed 2: AWP = 1.13031...
You effectively have 4 different zoom sensitivities (that don't have any correlation to each other in terms of feel). You can try one of these values directly, or alternatively, you can replicate the scaling behaviour.
Assuming Apex is at 90 fov (cl_fovScale 1.285714) to match CS:GO, these will be the values that replicates CS:GO's scaling system with your 0.89 multiplier:
Holo (77.14 fov) = 0.956606...
ADS (70.71 fov) = 0.985569...
6x Scope (17.12 fov) = 1.12474...
10x Scope (10.3 fov) = 1.13013...
Averaged Magnification (47.2 fov) = 1.06836...
Since you can't set a unique value for every weapon, you just have to settle for one of them. If you match Holo or ADS, the Scopes will be slower than CS:GO. If you match to Scopes, the Holo & ADS will be too fast. A compromise will be to use the averaged magnification, which will be the most balanced option. Choice is up to you whether or not to make one weapon perfect, or balance all weapons.
Either choose the direct sensitivity multiplier that you have been using in CS:GO (the first box of values), or choose a sensitivity multiplier that uses the CSGO scaling method (second box of values).
Calculations:
SG 553 / AUG = 0.89 * 45/90 * tan(90 * pi/360)/tan(45 * pi/360)
Zoomed 1: AWP, SSG 08, G3SG1, SCAR-20 = 0.89 * 40/90 * tan(90 * pi/360)/tan(40 * pi/360)
Zoomed 2: SSG 08, G3SG1, SCAR-20 = 0.89 * 15/90 * tan(90 * pi/360)/tan(15 * pi/360)
Zoomed 2: AWP = 0.89 * 10/90 * tan(90 * pi/360)/tan(10 * pi/360)
Holo (77.14 fov) = 0.89 * 77.14/90 * tan(90 * pi/360)/tan(77.14 * pi/360)
ADS (70.71 fov) = 0.89 * 70.71/90 * tan(90 * pi/360)/tan(70.71 * pi/360)
6x Scope (17.12 fov) = 0.89 * 17.12/90 * tan(90 * pi/360)/tan(17.12 * pi/360)
10x Scope (10.3 fov) = 0.89 * 10.3/90 * tan(90 * pi/360)/tan(10.3 * pi/360)
Averaged fov = (360 * atan(1/4 * (tan(10.3 * pi/360) + tan(17.12 * pi/360) + tan(70.71 * pi/360) + tan(77.14 * pi/360))))/pi
