I finally worked around the problem by lifting the requirement to use the GUI for file share creation entirely. Instead, I documented the use of New-SmbShare as the share creation procedure. Adding shares in this way bypasses all pre-configuration checks the GUI wizard is performing, including the quota enumeration.
New-SmbShare -Name <ShareName> -ScopeName "<CAPName>" -Path "<LocalDirectoryToBeShared>" -FullAccess "Everyone" -Description "<Comment>"
The New-SmbShare cmdlet has been introduced with Server 2012 R2 / Windows 8.1. For previous (2012, 2008R2, 2008) version File Server clusters, you can borrow the NativeMethods class with which is importing the NetShareAdd function from Netapi32.dll from a script published along with an MSDN blog post about shares in Fileover Cluster scopes.
My significantly shortened version looks like this:

Usage is trivial:
[NativeMethods]::ShareFolder("<CAPname>", "<ShareName>", "<LocalDirectoryToBeShared>", "<Comment>")
The ShareFolder function returns 0 upon successful execution and finishes instantly, even with quotas enabled. To be run on one of the cluster nodes hosting the CAP / file server resource. You might have to fix share ACLs afterwards, as the default share creation ACL is just Everyone:Read and cannot be specified with this method.
