The following items from the DMG are included and useful:

• Dwarven Thrower
• Holy Avengers
• Instruments of the Bards
• Moonblades, but only if you are neutral good
• Prayer Beads
• 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 cast one spell per day)
• 7 kinds of wands, but you could already use those if you were a spellcaster e.g. a high-elf rogue
• Whelm
• All spell scrolls

Note that the PHB has no magic items.

Mostly these magic items give you potent spellcasting abilities, but some of them (the robe of the archmagi and the staff of power) also raise your AC. A rogue with a +3 shield and staff of power and appropriate Robe could have an AC as high as 30.

Moonblades are a special case where this feature gives a thief access to something truly uniquely powerful, though since that's a racial rather than class restriction it's not like you couldn't have had one anyways just by playing an elf or half-elf.

• this assumes you go with the RAI rather than RAW on this answer here, i.e. 'requires attunement by a spellcaster' counts as a class restriction bypassed by this feature instead of not.
