Koelsh, thanks for your screenshots — and confirmation of what the terms mean and the inconsistencies that abound among apps!
I'll stick to my tried-and-true method of main window taking up most of the screen (menu showing) with windows for the couple of other needed apps just visible to the right behind the main app. I quit apps i', not using routinely.
Right-hand dock (never the bottom default), with hide-and-show optional depending on which app or project I’m working on, e.g., if lots of spreadsheet columns, landscape page orientation, or two windows on the same doc in Word, one for text and the other for bibliography.
