The 2024 Warlock / Great Old One Level 10 Feature Eldritch Hex does allow Hex to affect Saving Throws, but that's the only way I know of offhand to make it do so.

Hex doesn't affect saving throws. Again. It will not help you with landing effects like he mentioned. Hex only affects ability checks. Aka like Acrobatics or Perception or Stealth etc.
It's been a while since I played a full Warlock and I still conflate ability checks and d20 checks. When I last played a pure Warlock it was before I saw the Sage Advice and was playing it as every d20 test with an ability is an ability check. I still don't often catch it when I reread the spell.
(Usually I play Artificers, Bards, Paladins, or Paladin/Warlocks.)
Edit/add: 3.8 is also not the effective value of Advantage or Disadvantage is all/most cases. They're variably effective depending how far from even odds you drift, with an even 50/50 being the most impactful.
I will have to find the original source for the estimate so that I can , but yes, the actual effect will depend on the difficulty of the roll. That doesn't prevent us from estimating the typical effectiveness. I assume that the original calculation was using on level challenges.
Edit: I don't think this is the one I read, but here is a breakdown in a Reddit post: No, +5 is not equivalent to advantage in (nearly) any situation. The conclusion is that the average is a 13.8. Since the the average on a d20 is 10.5, this looks suspiciously like someone subtracted 10 to get an "effective bonus" of 3.8 instead of subtracting 10.5 to get 3.3.
When you have Advantage or Disadvantage on Perception, the Passive Perception increases or decreases by 5, but the effect on typical rolls is not equivalent to +5 or -5.
3.8 is the ncrease in the average value rolled for a d20 based on the math in the video in the first post. So roughly a +4 to the roll rather than a +5.

What video are referencing? Is it this one by Stray Cat? If so, it has the same issue I mentioned where the average 1D20 roll is 10.5 and the average with advantage is 13.8 (a difference of 3.3, not 3.8 and it does not round off to 4).
I just brute forced out the numbers manually on a Google Sheet and I get that the average die roll with Advantage is 13.825 and the average with Disadvantage is 7.17. Subtracting out the 10.5, advantage is +3.325 and disadvantage is -3.33. Note that advantage and disadvantage affect skills and attacks/death saves differently. A 1 automatically misses an attack and counts as two failed death saves. A 20 automatically hits and heals 1 HP for death saves (essentially ending the need to make death saves). Skills, others saves, and other d20 tests do no automatically succeed or fail.
This means that the chance of succeeding a skill check that you need to roll higher than a 20 on is always 0%, but for an attack roll would 5% normally, 9.75% with advantage and 0.25% with disadvantage. Conversely if you need to roll a 1, most d20 tests always succeed, but an attack roll will miss 5% of the time, 0.25% with advantage.
I am not sure how to take into that into account to see the difference. Attempting to brute force it, the difference in odds on an attack roll versus a skill check is very minor. On an attack roll, the effect of advantage is roughly equivalent to +3.3725 and disadvantage is -3.3725. While a skill roll comes out +3.325 for advantage and -3.325 for disadvantage. I am not sure if I did something wrong (since this does not match the above calculation) or if incorporating needing a 1 to 20 to hit/succeed and then taking the average of the result normalized the data.

I never studied probability.
