Trade Journaling - What actually gets tracked?

I've been trying to get more serious about tracking my trades, mostly futures, $ES, $NQ, and $CL. Everyone says "journaling is key" to improvement, but I'm finding myself just listing entry/exit, profit/loss, and a vague "why" that often sounds like hindsight bias. It's not really helping me identify patterns or fundamental flaws beyond the obvious. For those of you who have successfully refined your process, what specific metrics or qualitative observations are you including that genuinely move the needle for your learning? Are you tagging trades by setup, market condition, psychological state? Just trying to figure out if I'm overcomplicating it or just not digging deep enough.
