What SSD is compatible with Mac Pro Mid 2014, 13"? To expand its capacity and up to how many Gigs could it be expanded?
My need is because I need more storage capacity
You can check with OWC for SSD upgrade options for your laptop (they may have a reseller in your region):

FYI, you do need to make sure that macOS 10.13+ has already been installed to the original Apple SSD before you can use a third party NVMe SSD since the macOS 10.13+ installers will update the laptop's system firmware to work with an NVMe SSD. After installing the third party NVMe SSD you will need to use macOS 10.13+ since they have the necessary NVMe SSD driver which earlier versions of macOS do not have.
I highly recommend keeping the original Apple SSD just in case it is ever needed later on. It can be useful for troubleshooting the laptop if you ever suspect the third party SSD has a problem.
