No tethering required (It is an M2 based computer) and it works with bluetooth keyboard and mouse. So, to answer your question, you will do whatever kinds of work you do today.
Of course there's workarounds (I used GitHub Codespaces for a while on my iPad and went without a Mac, and you could use the desktop streaming available on the headset), but they are no match for the same convenience you get by staying fully within Apple's walled garden.
