None of the packs that are "by Minecraft" change the menus, hotbar, or backrgound panorama. However, the exact same pack on the old Xbox One edition does. The textures that should be changed include:

• Font color
• Hotbar
• Hunger shank (all variations)
• Hearts (all variations)
• XP Bar (Full and empty)
• Panorama on loading screens
• Menu outline
• Menu buttons
• Menu slider
• Menu checkbox
• Menu toggle
• Menu [X]
• All in-game menus, such as furnace, inventory, and crafting table
• Armor, offhand, saddle, and carpet slots
• Touch buttons (these aren't on Xbox One Edition, but PureBDCraft changes them so first-party packs should be able to as well)
• Map coloring (they are usually altered slightly from pack to pack)
• In the Plastic texture pack's case, the Steve skin
• The floating text when an item is selected in an inventory menu
• "Minecraft" logo (for example, it's changed to Minecraft: Skyrim Edition in the Skyrim pack)
• Crosshair

There are probably more that I forgot about, but these would be a good place to start. The texture packs that are affected are:

• Plastic
• Natural
• Fantasy
• City
• Pattern
• Festive
• Cartoon
• Steampunk
• Adventure Time
• Candy
• Greek Mythology
• Chinese Mythology
• Skyrim
• Fallout

Adding textures for the menus is important particularly because the old console editions have these textures, so switching to the new one would essentially be a downgrade.

The images below all use the Fantasy texture pack for comparisons. I've added the logo of the version on top of the image so you can easily tell which version the screenshot is from.
