I'm a bit confused on this point still as if the whole purpose of pg_basebackup is to be streaming ... then we should be defaulting to fetch mode still?
No. Since I thought streaming is the whole purpose of pg_basebackup, I questioned the utility of every other method except --wal-method=streaming.

In terms of using pgbackrest to initialize a replica ... that's basically running 'pgbackrest restore --type=standby'? There's really not much more to it than that. pgbackrest will set up the restored system to replay from the WAL in the archive, you'd just need to configure primary_conninfo so that the replica will attempt to connect to the primary once it's caught up with all of the WAL in the archive.
I haven't examined it closely enough. What little looking that I did made me wonder whether PgBackRest handled all the replication itself, or whether it just initialized everything and then let physical replication using replication slots take over.
