When you ask what data should be paying attention to, that should be depends on your objective. Do you want to predict something? Identify anomalies? In the end, what matters is understanding the meaning and relations of these data, rather than throwing them in to some ML framework and hoping to get something out.

Prediction and anomalies are not objectives but of the 4 listed, I would say the primary objective is identifying a trend in the data to know whether the data is moving in a specific direction—increasing or decreasing in value.

I already added linear regression marks that draws linear regression lines with confidence bands[1] to my Observable plots but they do not give me a “value” so I need to manually look at the graphs and read the red line.
