I can toggle between virtual desktops with a keystroke in Windows, too! I have mine set to CTRL-WINDOWS-arrow. Let me know what you're having trouble with and I can help you get Windows 10 set up the way you want.
I agree with the grandparent poster that the Windows situation is very bad compared to something like i3.
I highly recommend using multiple desktops with dedicated hotkeys over alt+tab to switch between applications. Much much faster to press fn+cmd+<h, j , k, l> and immediately bring up the application you want than to tab until you find the application you are looking for.
Also very useful: the windows-key shortcut overview that the PowerToys added (keep the windows-keypressed for a second or two to bring it up).
I only use W10 as a secondary OS and never used windows as main since XP/2000. So far never got to dig deeper into this. It seems to me that out of the box a lot of the functionality is there, but there are also a lot of related third party (often paid) tools.
What are some good combination of tools (third party, paid or not) and settings for a more keyboard centric i guess you could call it, setup of Windows? At the moment to me it feels a bit like, that I could do everything with just keyboard but I'm not meant to.
