You can automate #1 by abusing SSH_ASKPASS.  It's pretty clunky though, 
plus it'll end poorly if you need to interact to authenticate.

$ ssh -o hostkeyalias=test localhost
The authenticity of host 'test (127.0.0.1)' can't be established.
ED25519 key fingerprint is SHA256:[etc].
Are you sure you want to continue connecting (yes/no/[fingerprint] ^C

$ cat >~/bin/askpass
#!/bin/sh
echo SHA256:[etc]
^D
$ chmod a+x ~/bin/askpass
$ SSH_ASKPASS=~/bin/askpass SSH_ASKPASS_REQUIRE=force ssh -o
hostkeyalias=test localhost
Warning: Permanently added 'test' (ED25519) to the list of known hosts.
