It might not be a good idea if you have any concern that the company you work for may ever be involved in litigation. This was part of the training when I joined Microsoft, many years ago, as a result of the big antitrust trial: anything at all that you do on your work computer or the company network might someday be subject to discovery. I have since maintained a strict separation between work accounts, data, and activities, which exist only on company-owned hardware, and my own personal data, which only lives on my own personal hardware.

Some companies are strict about firewalling corporate data in, but I think it's also important for us to protect ourselves by keeping our personal data out.

This is extremely good advice. It’s frequently at odds with convenience, since things like iPhone screen mirroring, iPad as a 2nd display, etc. practically beg for you to sign into your work laptop with your personal Apple ID. All I can say is resist the urge to do such things.

I do keep a browser profile on the work machine signed into personal accounts, and do everything personal only in that browser, but even that is probably a mistake. Screen-sharing to home would be a much better compromise, unfortunately my gigabit internet comes with like 50Mbps upload so screen sharing sucks.
