From my experience, passkeys work great in the Apple ecosystem. Adding a passkey for a new site on my Mac results in that passkey syncing automatically on my iPhone and iPad via iCloud.
"But what if I lose all of my Apple devices in a freak boating accident?" people often ask or something like it. Apple has a procedure for this [1].
You can contact your "recovery contact" (a trusted friend or family member) that can help authenticate you to regain access to your account, especially if you're locked out or forgot your password.
On a new device, you login to your Apple account, make sure iCloud Keychain is enabled, and all of your credentials, including your passkeys, sync to your device.
I get it—not everyone wants or uses iCloud. Apparently, you can use 3rd party password managers like 1Password, Bitwarden, etc. to backup and recover your passkeys to use elsewhere.
Here's a video of an export from 1Password to the Passwords app on an iPhone [2].
