Googling also works for Word, but I practically never need it there. It's just so easy to find solutions to those questions that you barely perceive them as such. I even figured out the shortcuts just by trying something that seemed to make sense (fyi: Italics is Ctrl+I, bold is Ctrl+B; changing indentation levels in a list is Alt+Shift+Arrow, getting out of the list indentation requires three times backspace, which I agree doesn't make sense, but it's easy enough to figure out within seconds of the first encounter; and yeah, you can google those if you want). In LaTeX I need to switch to a different window get to Google much more frequently, and I find that breaks my flow. I don't see how this could be framed as anyhting but a disadvantage.

Anything becomes easy if you practice it enough, but I find both the 'onboarding' as well as the 'steady-state' productivity higher in Word, because you spend next to no time looking for how stuff works and instead focus on your content. Yes, LaTeX formatting generally looks better (eg spacing, LaTeX even lets you adjust the spacing between individual characters), but looks come second to content imho.
