What chip can I clone a ISO 14443-3A card (Mifare DESFire EV2 4k card) onto?

Yeah, Most llikely.

One thing to consider would be the DESFire of your work, and how it is implemented.
If it has been set up “properly” then a FlexDF2 would be your best bet ( xDF2 will not couple as well with the readers as a Flex ) and get it enrolled

IF, your work system simply uses UID for access ( Unlikely, but possible ), you could in theory get your Apex Flex enrolled and this would work.
To test this, Scan your Work card with TagInfo

You would be looking for something like this… Infact, Hoping you don’t have this
