Not so much of a con. I now automatically add my public keys to a
machine as part of the bring-up process after installation.

Nope. rsync over ssh handles that.

I use ftp only for one server where I don't have rsync over ssh
service. One of several reasons I want to abandon that server.

I don't use cloud storage other than my own nextcloud server.

It depends on what I am doing. I use rsnapshot for backups. scp for
one-offs. I use emacs' tramp mode to edit files on other machines. (It
uses scp by default bu you can specify other transport mechanisms.)
I also use unison, nextcloud and syncthing to sync user data between my
desktop and my laptops. The former is manual for occasional use, the
latter two run automatically as files change. The first two I use when I
am away to back up the laptop; the latter I don't use when away. (Hotels
tend to have crappy networks.)
