Netflix differed in subscriptions?

I want to make a Netflix but don't know exactly which subscription. I need it for 2 people on 3 devices (2x cell phone, 1x TV)

Which subscription is more appropriate or are these factors irrelevant

That for 11.99 euro.

So I have the most expensive subscription for 4 devices. Currently use 8-9 devices.

I would take the standard subscription, the second one.

The subscriptions differ only in the number of possible devices and the resolution. The middle one should be enough for you. You can change it at any time.

But that is only for 2 devices or

At the same time, as far as I know, you can change which 2 devices you want at any time

The middle the number of devices is irrelevant only how many bones you want to look at is important so 2

The subscriptions are for an infinite number of devices… Only for either 2 or 4 simultaneous streams…
