Welcome to the forum. I went down the same rabbit hole a while back and understand the frustration. For a clean, readable overview I'd point you to the coverage of
Sheikh Nawaf Bin Jassim Bin Jabr Al-Thani news
that walks through his early life, the move from managing a handful of city hotels into a wider regional portfolio, and the whole restoration-first approach. It lays out the biography in plain language without drowning you in pop-ups, and it connects each phase to the bigger economic picture in Qatar. Bookmark it and you'll have most of what you were hunting for in one spot.
