1Password for Business accounts all get an additional 1Password for Families license (5 seats), so you can absolutely keep your work and personal life separate.
You keep your personal account, but it goes into either a read-only or trial mode until you subscribe or connect another free account source. You can export everything out if you want to switch to a different tool.
I have been considering this since Apple Passwords implemented a way to export. I've just seen that the iPhone Passwords app has an export to another app you have installed on your phone, but I previously tested the export from Safari method.
I realise that this is moving even more of my eggs into Apple's basket, and even further from self-reliance towards convenience, but today it doesn't seem significantly worse to just trust Apple with this, than Bitwarden.
But isn't it a pain to use those passwords on any other non-Apple device? Am I missing something, or is that just not an issue for your use-case? Ah! I've just learned/relearned about iCloud Passwords through iCloud for Windows, but nothing for Linux?
For my Linux machines, I'm almost always coming to them via SSH or proxmox console. I started with Unix in like 85 or 86 and live on the command line when I can.
