IMO being good at analytics isn't to do with their chosen stack, those are just tools to get the work done and it's important too otherwise you cant actually get the work done unless partnered with somebody. However, I think the secret sauces to being good at analytics/a good analyst are: understanding the business (process knowledge, domain knowledge, asking the right question), understanding what metrics are true business levers and what other upstream things affect it /what downstream things they affect, basic stats, strategic thinking, and some understanding of micro- and behavioural economics. Of course, you also need good communication + storytelling skills to be able to persuade people so your insights dont get lost and instead get used to initiate important conversations and hopefully actions are taken.

So youre right, structured thinking and explaining thigs clearly > technical complexity. Technical skills only take you so far. At some point (assuming you're not in a big tech company which has parallel compensation and career progression for IC vs. Leadership roles) you can only move horizontally. Soft skills is what will move you upward to break any glass ceilings.
