This is a cardinal rule for me. I have a personally-owned PC that is used for my work, but it is exclusively used for that purpose. The only extent of personal use on my work PC is this website. Everything else I will RDP from my work PC to a personal machine, or physically go use it. I've extended this ideology to other areas. I have a separate physical machine I use only for banking and stock transactions. It's kinda like a shitty DIY Bloomberg terminal in my kitchen.
I find that having multiple physical computers, each with a very specific purpose, is an excellent way to context switch and maintain that psychological isolation between duties. There are definitely security/privacy benefits as well, but I hesitate to delve into that rabbit hole of a discussion here.

Even that would make me nervous, given keyloggers.
One benefit of working from home for the last few months is that there's no temptation to do anything non-work related on my company machine when my personal machines are right there.
I strongly agree. I go one level further. As an independent consultant, I have multiple clients (usually around 3-4 at any given time). I use a different laptop and mobile device for every client. I would take to them to client site -- when travel was a thing. I also use different VPCs on the cloud for each of them. And I have a different set of machines for my own business. This allows clients to specify whatever software policy they like on machines that connect to their network, wit out affecting anything else I do. I wipe the hard disks of the the relevant machines clean after end of the engagement. None of my clients has demanded that I install any 'bossware', primarily because I'm only paid on outcomes, not effort. So they don't really care how I do the work.
