The player base body does not come with arms attached — this made it easier for the developers to switch out the different kinds of cyber arms. It makes everything harder for you.
Default Arms
You can look up the component names and their properties in the .ent files per body gender in these folders (the file names will start with a0_).
Female
Female arms are using different meshes for the first person perspective. You will find this is a common theme.
Cyber arms are complex, with active and inactive states, and in the case of the female body, separate entities and meshes for the inactive state in First and Third Person Perspectives.
They also have separate Rigs and Animations, which are not included here to avoid complete information overload.
To add insult to injury, if you dig into the actual meshes in use, you will find some cases of wa meshes being used by ma components and vice versa. But there's a mod for that.
Monowire Arms
Female
Note that the same component name is used for all arm states, even when declared in different .ent files.
These two items are represented identically by a game item internally called the `weapon_grip`. However, the Weapon Grip is not a normal component, added or removed from the body, in the way that the arms themselves are. Instead, it is placed into an attachment slot. This has big implications for anyone hoping to manipulate them. As it is not part of the player puppet, you cannot manipulate it using Part Overrides, or Hiding Tags. Additionally, the game itself has weird and inconsistent rules for when to show the grip, and when the actually put the item into the attachment slot.
As a result, most people give up and use a mod that deletes the actual Weapon Grip meshes. It is possible to manage the visibility via Codeware scripting, but even that isn't straight forward.

Hiding Arms
There's no easy way to hide arms except by getting rid of everything - The ArchiveXL hide_Arms tag actually hides everything with an a0_ prefix. For more information, check ArchiveXL tags
If you want to selectively hide arm meshes or sub-meshes you will need to become familiar with all the contents of this page, and the chances that you can do anything elegantly are slim.
Remember: Arms are why we can't have nice things.
For reasons best known to CDPR, the monowire arm meshes displayed in game for fem V are different from the ones linked in the components listed above. They have different geometry and submesh counts.
In order to hide fem V monowire arms you have to hide specifc submeshes on each arm that otherwise don't seem to exist in the linked meshes. The submeshes are [0, 4, 5, 6, 7] for the left arm and [0, 2, 5, 6, 7] for the right arm. They are written accordingly in the list below.
