I can't dedicate that sort of time in a shot generally, certainly not with the extra time to get into the right headspace. I tend to aim for paragraph-size thoughts, expounding as and when necessary.
I actively work to avoid typing, because I genuinely enjoy fountain pens and because Lord knows I type more than enough in my day job. I end up with very different outcome styles typing vs. hand writing, the former tends to be more business-ready, the latter tends to be much more true to the actual feelings/thoughts I'm trying to capture.
One of my most frequent use cases for journaling is to keep running logs of interactions with various organizations, in a mostly chronological way that I can later follow. Currently juggling a number of insurance companies, doctors, and a bunch of other related stuff and I'd be completely lost if I didn't have a way to easily see whom I spoke to about what, when, and what documentation I sent where. That part is tailor-made for handwriting, from where I sit, if I try to type contemporaneous notes they invariably end up being closer to a transcript than to useful bullet points.
There is no right or wrong way to do this, only what works for you.
