If you only allow connections from localhost or your lan address, I  
don't see why you couldn't stick with plain auth especially since  
it's your home lan and you can trust all the users on it.

Cram-md5 however would allow you to open the server to the outside  
wan, if combined with some auth access to the postix also (I use cram- 
md5 / digest-md5 for both with the same sasldb). Then you can use for  
example your laptop somewhere else and use your regular mail client.  
Personally I'd prefer the latter.

Another option would be using vpn and plain auth, but that's to much  
OT I guess.
