Hi Devin,
This resource documents the choices pretty well I think
https://stribika.github.io/2015/01/04/secure-secure-shell.html
Author has made some modifications up to Jan 2016
https://github.com/stribika/stribika.github.io/commits/master/_posts/2015-01-04-secure-secure-shell.md
The short answer then is ed25519 or rsa4096, disable both dsa and ecdsa.
Even 6.5p1 shipped with 9.3 supports ed25519.
Cheers,
Bernard.

Which would you use?
ECDSA?

"" In the wake of the exposure of Dual_EC_DRBG as "an NSA undercover
operation", cryptography experts have also expressed concern over the
security of the NIST recommended elliptic curves,[31]
<https://en.wikipedia.org/wiki/Elliptic_curve_cryptography#cite_note-31>
suggesting a return to encryption based on non-elliptic-curve groups.

Or perhaps RSA? (as des@ recommends)
(not necessarily to Glen but anyone that wants to answer)

This is a heads-up that OpenSSH keys are deprecated upstream by
OpenSSH,
and will be deprecated effective 11.0-RELEASE (and preceeding RCs).
Please see r303716 for details on the relevant commit, but upstream no
longer considers them secure. Please replace DSA keys with ECDSA or
RSA
keys as soon as possible, otherwise there will be issues when
upgrading
from 11.0-BETA4 to the subsequent 11.0 build, but most definitely the
11.0-RELEASE build.
