I have been using Mac since 2018 daily on my day job and I still get confused by the symbols. I wish there was some system option to always display them as words or abbreviations (CMD etc) instead.
But I did get used to the navigation and basic shortcuts after a while. Using the terminal/keyboard/IDE shortcuts (which I can set up myself) for most of the work helps a lot.
Finder is still terrible though.
Finder has its whole set of keyboard navigation shortcuts, like command + up arrow to go to parent, command + down arrow to open, ⌘3 for column view, ⌘⇧D for desktop, ⌘⇧H for home, ⌘⇧G for "go to"… I am very fond of the Finder’s navigation and as a long-time Mac user it still feels pretty clunky to try and get around on Windows. Both Windows and Mac are getting worse but it seems like Microsoft is making it worse faster, with OneDrive.
A lot of the Finder shortcuts work in the save / open dialogs in apps, although they broke some of the ergonomics of those dialogs years back.
They're written underneath the symbols on most (all?) Mac keyboards. At the very least, it's that way on my current MacBook, and my previous. I think they're also written on the magic keyboard I have as well.
