Kudos for learning a lot in a short time. Many take longer to recapitulate these ideas, I certainly did. Alas, this is the standard buy-side quant curriculum. IDK where SOTA is these days but you have to a different edge because as you highlighted, it's so easy to reproduce the basics.
As a fun aside, I find it quite fascinating when you see a particular signal go dead overnight.
I recall one particular overnight reversion strategy in my local market which in the 90s and early 2000s had like a 45 degree straight line equity curve and then overnight in 2011 it just went flat. Someone clearly turned on a model that day and started trading it. It's a small market here so I know who it was but I still find it fascinating how clearly it showed up in the data.
