Welcome to ECN Forums!
Keep in mind that the NEC is not a design tool.
From a safety related study, the design professional has the ability to exceed the requirements within the NEC regarding GFI protection. I guess, if one wanted to, one could install AFCI protection on 15/20 amp, 120 volt receptacles within office areas.
My point, if safety is the concern, by all means install the GFI receptacles; you may want 'spec' grade devices also.
