If your company Mac is locked down to the point where you couldn't just create a separate account on it that is tied to your iCloud account, then it is also unlikely that they would allow you to hook up another device to their network and your work computer in order to have this convenience.

(My partner is corpo; I'm startup, but have worked at corpos. No thanks.)

Better to keep it all owned by the company, in my opinion, and have them issue you an iPad for this express purpose.

There’s plenty of reasons why you would want to have a separate Apple ID for a company Mac that have nothing to do with overly restrictive permissions from IT.

The main one being a complete separation of calls, messages, calendar, notes and reminders. For my own sake more than for my employers sake.

And many employees with company phones already have that separation. iPhone and Mac is not that uncommon to provide for employees. But an iPad on top? I think that’s gonna be much harder to find

And edit: a Vision Pro on top…

Sure you can create a separate account on your company Mac. But there's no assurance that whatever work resources needed would be available on that second separate account.

If your work is on the traditional model of perimeter protection and trusted intranet, a non-work device can't join the network as you have correctly pointed out. If your work is on the newer BeyondCorp style model, switching to a second account on your computer is going to invalidate the device trust needed to access work resources.
