USAF Credentialing: Which of these is worth it?

[OfficerA]

Certified Administrative Professional (CAP) - International Association of Administrative Professionals (entry level)

Certified Customer Service Specialist (CSS) - Electronics Technicians Association, International (ETA-I) (ETA International - Welcome)

Professional in Human Resources (PHR)

Senior Professional in Human Resources (SPHR)

Certified Employee Benefit Specialist - International Foundation of Employee Benefit Plans

So the Air Force recently adjusted the lifetime credentialing that a member is allowed to pursue, so that it ties more now with one's career (which to me makes sense anyway). I asked about this before but didn't really have the time for it; now I'm kind of stuck with these anyway, pending any other changes the USAF wants to add on.

So which of these would be worth it outside the USAF? I'm good for within, and I highly doubt I can actually use any of these to get ahead of the pack, so to speak (especially as things only get political much later in the game). Still, I wouldn't want to waste an opportunity like this when the Air Force is offering it, so I welcome whatever thoughts you all may have.

PHR and SPHR are quite handy if you ever have interest to go into HR or certain management roles. Benefits specialist is the same - but is niched exclusively to an HR role. No idea on the others; none of my employer's local positions call for such things.
