Org mode with some fairly well-worn templates. My daily log is in datetree format. I have a few agenda options so at my weekly meeting I can get a quick review of what I've done during the week (or quarter if I'm writing quarterly notes).

If I go to a meeting I take notes with pen and paper and transfer them in elaborated form when I return. Good note taking is a skill, though!

I dabbled with an ultra quick template (F12 to write a single line in a mega list with a date stamp at the front of each item, no options, no slowdown). I found the discipline of taking slow notes at the end of every task or day much better than effectively tweeting my day to my future self.

One thing that I've found difficult is having task/project journals that work easily into this flow. Tags help but I found I was duplicating everything in changelogs.
