We just figured it out, the asr9k in 4.1.1 has this:
Full-duplex, 1000Mb/s, SXFD, link type is force-up
Adding negotiation auto under every fiber SFP interface having the issue has
resolved it:
Full-duplex, 1000Mb/s, SXFD, link type is autonegotiation
Thanks!

ASR only supports the 100m-fx GLC. The rest need to be SFP to work at all.
