The all around best choice would be VAX/VMS v5.5-2.  You can get Hobbyist licenses.  The OS was available as part of the Hobbyist program.  If you add a SCSI adapter, you can hopefully attach a CD.  IIRC, it will run up to either v7.2 or 7.3, at least I know I had v7.2 on a MicroVAX III (well, technically I still do, if it will boot).

Ultrix would also be available.

What I did though was I gave it a brain transplant, and converted mine to a PDP-11 once I got a better VAX.

I need to invest in a couple of those SD adapters myself.  I’d really like to put one on one of my AlphaStation 200 4/233’s.  Hopefully they’ll still work.  It’s been years since I’ve done anything with my DEC HW. :-(
