Why isn't there a simple method that just varies slightly on different models, and if there is, what are the essential steps?
Have you looked at the Shimano manuals for your brakes? They give everything needed to know how to do it. The DM's are what you want to read.

And Park Tool usually has pretty good information and videos that can be trusted. Though I haven't watched theirs on hydraulic brakes

Don't overthink it. Hydraulic brakes are more simple than many want to make them out to be. Regardless of any of my discussion here for whether it's needed on a regular basis, perhaps you should just do bleed your brakes a few times so you'll know what to do when actually needed.
Though if your DIY experience involves frequent missteps and having to do things several times to get stuff working again, maybe that's a bad idea.
