Windows key is super-useful on Windows, and it gets better every version. Aside from the Win+Arrow combinations, which are probably among the most useful, other ones that I use daily are Win+. to bring up emoji keyboard, Win+V to bring up clipboard history, Win+T to navigate the quicklaunch/taskbar apps and (less frequently) Win+Plus and Win+Minus to zoom the display. There are some new settings shortcuts too like Win+A for mini-settings (like Android swipe from top), Win+I for proper settings and Win+P for projector settings. Plus there are all the old keypresses that have been around forever like Win+R run, Win+L lock workstation, Win+M minimize everything, Win+D for show desktop toggle, Win+S for search (used to be Win+F/find), Win+E explore... I think nowadays I use Windows button as much as I do Control and Shift. Alt is less useful since applications stopped having menus, but AltGr is great for international input. I suppose Win+Space is important to know too, if you switch keyboards a lot (I do).
