Good summary. One thing to note about org is it's not opinionated. Even the word "Todo" is up to you, in fact you can just tell it a bunch of "not done" keywords and a bunch of "done" ones. Over the years I've tweaked these. For example I use STARTED for tasks that I've begun but not yet finished, because I hate starting things but but not finishing them. I've set my agenda views to display these right at the top. Similarly I've added more resolutions like DELEGATED.
This flexibility means you can bend it to rather odd requirements. For example, in my current job I'm required to track time against project codes, but I have to scale the proportion against the hours I'm contracted for (it's a tax thing, I'm told). Org supports clocking in/out of things. It doesn't know what those things are, they are just items in the outline. So I structure my todos under the project codes then track time against those tasks or just directly to the project. Then I have an agenda view which shows me totals for each project and a column scaling the proportions to the total contracted hours over the period.
But you might have completely different requirements. You might want a flat backlog and to "refile" tasks into "sprints" when they get properly defined then set a deadline on the whole sprint. Org supports it all because it doesn't really care that much. Seeing people struggle with the likes of Jira becomes rather comical.
