I've been using multiple profiles in Chrome for years for keeping things separate… right up until my company started using Google's centralized browser/device management which infects the entire browser not just the single profile that is tied to my corporate Google account. Specifically, they forced a homepage setting browser-wide that can not be changed on a per-profile basis.
So multiple profiles are seemingly difficult to get right/fully isolated. I hope Firefox doesn't have similar limitations.
My guess would be that your company probably wants the MDM profile to be globally enabled or is alternatively limited by their MDM's or Chrome's capabilities.

I hope Firefox doesn't implement MDM at all, or at least provides a non-negotiable way for the user to opt out of it on a per-profile basis.

Personal profiles on your work computer? That's a no for me. The only account I brought to my work computer was my Github's one. And I'd rather use Incognito Mode or another browser if I want to do something I did not want associated with my google account.
Firefox does have profiles and has had for as long as I’ve needed them. For some reason they’ve always been hidden away and needed different args on start to change the profile being started, or the use of an extension to allow profile switching. I don’t use them anymore but from what I remember they worked well and were very isolated. Hopefully they’re using the current implementation and just making it more user friendly?
You can use the url about:profiles to manage profiles too, which is still hidden away and not a great UI, but at least you don't need to use an extension or the command line.
As of a recent update, the Profile Manager is available as a startup option if you right click the ff icon (on gnome at least, i assume this was implemented cross platform)
It's not just a GNOME thing, but it might not be that cross-platform. On Linux, there's a firefox.desktop file that describes the application to your DE/launcher, and it looks like this on my box:
Holding the "option" key is even somewhat of an UI convention on macOS to allow opening an alternative media library (e.g. for Photos, Music aka iTunes etc.), yet Firefox maps it to "startup in safe mode".
