I am pretty convinced by the scientific consensus that LDL levels (even by themselves) are strongly predictive of Atherogenesis and overall CVD risk.

"An overwhelming body of multiple, converging lines of evidence has established a causal role for LDL in atherosclerosis and CHD/CVD progression as a fact, beyond a hypothesis."

https://sigmanutrition.com/lipids/ has a very good overall survey of the field.

Cholesterol is only a problem when it forms plaques on arterial walls. While reducing blood cholesterol is one way to slow the growth of those plaques, it it better to prevent the damage which causes those plaques to form in the first place.

Seems the number one recommendation is "Eating a diet low in saturated fats and cholesterol, with less sugars and simple carbohydrates", what do you propose and whats the proof?

I don't know where you're getting that recommendation but it's at least partly misinformation.

“Cholesterol is not considered a nutrient of concern for overconsumption.”

The latest take seems to be related to ApoB numbers (which correlate to LDL numbers).

I resisted for a long time but I'm finally swayed and am medicating to take the ApoB levels down (diet and exercise can help but medication seems to be the strongest factor).
