The following items from the DMG are included and useful:
Instruments of the Bards
Moonblades, but only if you are neutral good
Robe of the Archmagi (but only if its alignment matches) (15+Dex AC and bonuses against spells)
Rod of Resurrection
11 different kinds of staves
Tome of the Stilled Tongue (bonus action ...
As mentioned by Krzysztof Skibiński, a spell book is not a magic item. The Thief Rogue's sub-class ability Use Magic Device allows your rogue to use a magic item that they normally would not be allowed to use.
For instance, a Rod of Resurrection (DMG, p. 197) normally only requires attunement by a Cleric, Druid, or Paladin to be used. This ability would ...
Everywhere that it says "the poison you choose", it means, the one that you choose when you take the move. From a very literal reading, you could say that each time this phrase occurs it's a separate choice, but I would not interpret it that way. (It would be clearer if they simply said "that poison", to obviously refer back to the first "choose as poison"....
Wizard's Spellbook is not a magic item. It's their Spellcasting class feature that allows them to prepare spells from their (and only their) book, which they can later cast.
As a student of arcane magic, you have a spellbook containing spells that show the first glimmerings of your true power. (...)

The spice pouch requires an action, so it doesn't work with Fast Hands
The description of Heward's handy spice pouch says:
While holding the pouch, you can use an action to expend 1 of its charges, speak the name of any nonmagical food seasoning [...]
— Xanathar's Guide to Everything, p. 137
That action is a special action option given by the magic item (...
You're thinking of "Brewer".
When you have time to gather materials and a safe place to brew you can create three doses of any one poison you've used before.
-- "The Thief", via the Github.
If you were meant to be able to create three doses of any poison from the start, this move would be useless to you. So it should be interpreted that ...
Thief Rogues do get a Dexterity Ability Boost
All classes, regardless of any other choice they make, get an Ability Boost in their Class (or Spell) DC Ability. The Thief gives up the option to choose Strength or Charisma (granted by the Ruffian and Scoundrel rackets respectively), and must take Dexterity for this choice.
The key ability for rogues says "Dexterity or other". As you noted, the "other" options come from your racket. Therefore, no matter which racket you pick you may still choose to have dexterity be your key ability and get a boost to it. The specifics of the thief racket don't change this.
However, to answer your question more directly, the thief racket ...
The Sword of Zariel is a possible candidate.
It is unclear if the wording of Use Magic Device changes how destroying the Sword of Zariel works, so it will be up to the DM, but it is still worth mentioning in response to this question.
From Baldur's Gate: Descent into Avernus, concerning the destruction of the Sword of Zariel:
Again, it is unclear of Use ...
It is worth noting that the artificer has the same wording listed in its class description of similar ability. Mainly important because it was released much later so at the very least, it is unlikely to simply be an error.
You ignore all class, race, spell, and level requirements on attuning to or using a magic item.
However as for Actual applications: One ...
