I heard NFS is self-tuning in cluster-mode but am not sure how to (or we need to) tune things like window sizes in Cluster-Mode... Are there cluster commands for these, is it recommended to "node run options" to the dblade of every node or is it not best practice to modify these for cluster-mode like 7-mode?
Some examples of tuning done on may 7-mode installs

I prefer to say "NFS is optimised in Cluster-Mode"
The ability to tune 'max_mpx' parameter has been introduced in 8.1.1 Cluster-Mode under the 'vserver cifs options' command directory. I do not believe the rest of the commands you have listed have similar settings in the shipping version of Cluster-Mode. There are plans to introduce the ability to tune of these parameters in upcoming versions of Cluster-Mode.
If there are systems that have non-default values for these parameters and the customer wishes to move the data to Cluster-Mode, please engage with a local CMET resource to discuss your options.
Hope this helps.
