Destiny 2 Witch Queen Deluxe pack purchased on wrong gamer account - what now?

Nothing can be transferred between accounts. Unfortunately you would have had to request a refund when it was first purchased and then repurchase it on the correct account. Since it's been so long, that would no longer be possible.

So the content is playable on the xbox by all users, the "Season" content, however, is only playable by the purchaser? Did I get that correct?

Ok, this helps out tremendously. Thanks so much. I'll be more careful going forward.

It's how Bungie allows sharing to be done. They consider the season passes to be in-game content which isn't shareable.

Thank you Smwutches.

I'm also curious why the purchased content is not available to all accounts in the family? Is that not normally a thing, or am I going about this the wrong way?

Hey belial, how are you today? Hope you're well.

In that case, Belial, since the Bungie 30th Anniversary Bundle is already included in The Witch Queen Deluxe edition :

What I advise you to do, is to wait for The Witch Queen Deluxe purchase to be finalized, and when it completes, ask for the refund on the Bungie 30th Anniversary Bundle.
