>This is solved by passkey-implementing software and devices (with Bluetooth) allowing you to log in with a QR code (Webauthn via CTAP hybrid transport).
Ok but how do I share my Netflix or Spotify accounts for example with those?

If they also allow passkeys as an alternative form of login that doesn't need 2FA you can use those to make the account sharing more secure.
When setting up sharing with someone first change the password to something else, and then share the account name and password. After they log in the can add a passkey to the account on their device or devices.
Then you can change the password back to your real password. When they want to use the account they login with their passkey.
If the service doesn't accept login passkeys but does allows passkeys for 2FA, you have to use real password sharing, but at least they can have a passkey for 2FA which may be easier than how you know handle 2FA.
How do people handle 2FA with account sharing? If the site uses TOTP you can give them the QR code that you received back when you made the account (you do save a screenshot of such QR codes for backup, right?).
But how do you handle SMS 2FA, which seems to be far more commonly offered than TOTP?
For email 2FA I suppose you could set up a filter on your incoming mail that forwards any incoming code emails to the people you shared with, and hope that the time limit on the code is long enough for this to work.
However, passkeys can and are available to be shared via password managers. They’re not locked to the secure chip on the device where they live usually. iOS’ Passwords app has a share button and 1Password lets you share passkey-containing items.
In fact, the QR code login feature makes it even easier to do a one-time sign in to your account for a friend, if you don’t want them to be able to login to your account indefinitely.
0: Netflix doesn’t support passkeys because their main audience is people signing in via smart TVs and whatnot, which largely don’t support CTAP or Webauthn in general)
Me to said companies: I will do what I want.
Me to company: Damn, guess you shouldn't have been an asshole about it, kind of backfired on you.
Even if you use TOTP, it's not designed to be shared, for example look up what hoops you need to jump through to export a single TOTP code in Google Authenticator. And they used to not even have that option; they told you to set up multiple TOTP codes on each website instead. Even on 1password I had to look up a tutorial on how to import a TOTP code cause the menu is in a very non-obvious and deep spot.
