Not sure I understand, steering racks are full of power steering oil, if you on about lubricating the universal joint that joins the column to the rack then any decent quality grease will do, I normally give bits like that a quick squirt with some lithium based aerosol grease.

If its a rack and pinion, that involves metal to metal contact without roller bearing skid considerations, so a moly and/or EP containing grease might be appropriate, as sold for inside CV boots (not of course in Taiwan).

I ordered some Comma stuff from the sadly now defunct Pilrig Motors,though it was cheaper on’t nyet. Should be pretty widely available

I wouldn't have thought it would make much difference where the drive comes from, hydraulic pump, EMF or biceps.

You MIGHT find they specify something in a meaningful fashion that is actually obtainable, but probably not
