How do I set up game sharing for all of these scenarios?

Hello, I read your post, and I believe I understand your situation. Xbox Ambassadors are here to help.

May I take just a moment to make note of the intricacy of your charts! That took effort, I've never seen anything like it in these forums, and I'm quite impressed to be honest! I just received my new Xbox one X two days ago, and had quite a similar situation.
from what I had read, and to my understanding I thought any Xbox in my home would be able to play on my Xbox game pass ultimate subscription. Evidently, this is not the case, you can add users to the account on which owns the subscription. I myself opted to
go with a second Xbox game pass ultimate subscription. This way I have the ability to play the full range of games on both Xboxes at the same time.

I hope this helps.

I must answer. Newer saw anything like that in my ambassador time. You are just great! How to answer on something smart and funny like this? Anyway. To be able to play the same game on two Xboxes, the account which bought the game must be set as homeobox
account on S. In that case, anyone on S can share his games, apps, and subscriptions. On the other console, that same account must be logged in to play all its games. But it cannot share since it can have only one home box. If somebody else wants to play must
use this account. And I think that you can't play the same game at the same time on both consoles. So, I think that scenario 7 won't work. Obviously scenario 2 won't work since the owner of the game pass is not logged. The same for 9.

In order to share, the Ultimate, any accounts need to use the Home of the "dog" no matter what scenario. So if I'm reading them correctly, scenarios 3,4,5,and 6 are all set correctly for sharing if the cat is only going to be using the One S.

ok. Thanks for the help. How about this scenario.

Xbox 1 - Set as my Home Xbox with Gold, but uses separate free membership account.

Xbox 2- Set as Home Xbox with free membership, but I sign in and play with The Gold account.

Would this allow the two consoles to share Xbox Live? Or am I missing something here?

If the gold is tied to your account, you would be sharing gold in either scenario. You can only share gold on one console at a time. You can set another console as your Home console so you can share your gold there, and you can use your gold on any console
you sign into.

I can turn it on using the android app as well as the windows 10 app. Are all the game sharing/ streaming setting set properly on your console? also make sure all your apps are up to date. But I do think its your console settings.
