difference in sshd protocol options

[David Mehler]

Hello,

I just went through an interesting go tonight getting an android file
manager to connect via sftp to my FreeBSD 12.1 sshd server. I've got
two questions. Refering to the sshd_config man page the
HostKeyAlgorithms option and the PubkeyAcceptedKeyTypes options is
there a difference between the options (both of which appear in the
default) ssh-rsa and ssh-rsa-cert-v01 at openssh.com?

Thanks.
Dave.
