Happened to me many times. As my other colleagues, I ran a Linux VM inside macOS. The overhead is not that large and is totally worth the sanity. Of course I had to use a few corporate-managed macOS apps, like Zoom, or Outlook, but this is not a very big deal.
I’m in the same situation, have to use Mac for SOC2 reasons after having used Linux for 10 years. The apps are fine, it’s the KDE window management I miss the most, and a VM won’t really help there.
Why, running KDE in VirtualBox in full-screen mode must be fine :) At least, I did it breathlessly with Xfce, on much older Apple hardware, and it was... just fine.
(OTOH running text-mode Emacs from a headless VM in a full-screen built-in Terminal may suddenly feel sluggish. Kitty or WezTerm solves this.)
Last time I tried, it didn't work well (or at all) with multiple monitors.
The IT department must hate you. I’m not in IT but I think it’s hard to be compliant with some kinds of regulations if you allow end users to run VMs.
