"If the specified list begins with a '-' character, then the
specified key types (including wildcards)will be removed from the
default set instead of replacing them."
Only the first "-" indicates the specified patterns are to be removed,
the other ones form part of the patterns and thus don't match any
algorithms. You probably want something like:
$ sudo ./sshd -T -o 'PubkeyAcceptedAlgorithms
-ssh-rsa,ssh-rsa-cert-*,rsa*' | grep -i PubkeyAcceptedAlgorithms
pubkeyacceptedalgorithms

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
