On a modern laptop with resonable specs I would be surprised you would
be able to tell the difference with or without noatime.

For softdep, man mount has this to say:

softdep Mount an FFS file system using soft dependencies.
This option is only supported for compatibility and
has no effect on OpenBSD.

so that would be definitely skippable. I forget just when it was
made into a no-op on OpenBSD, but I think it's been like that for
at least a couple of releases.

Other followups from people with slightly less rapid-refresh memory
than myself may even provide the exact commit.
