If you used Arq with AWS's Glacier, that is not Arq's fault, but AWS's; Glacier is designed to be (extremely-)high-latency.

If you want low-latency restores, see my other comment: https://news.ycombinator.com/item?id=13000979. I've restored small, individual files with Arq + GCS several times, and each time takes just a few seconds.

All the other storage targets that Arq supports (Dropbox, S3, SFTP, Google Drive, etc.) should also be very fast to restore from.

Should, yes. My restore from SFTP over a LAN was going to be about 90 minutes.

I've never used SFTP with Arq. Did you investigate it any further? I'm sure the author would love a bug report.
