I remember playing the beta version a bit some time ago (it didn't want to work properly at first so I had to launch it by loading the first level from the command line), but I have deleted it since. One thing I remember very clearly is that the staring location in level 1 and the secret room that is near the gold key (and is a reference to the secret apartment in Duke3D's E1L1) were swapped. Also, you can't switch between single and dual UZIs once you pick the second one, just like in v1.0/1.1. Another thing, IIRC, the fists are on button 1, while the katana and the shurikens share button 2. The fist attack also includes the animation of Duke's mighty foot, albeit in brown pants, and the animation of Lo Wang striking with his palm (this one) is used along with the animation of him hitting with close fists (as in the regular versions). There's a clip of Lo Wang saying "Come get some!" (I suppose it's COMEGET2.VOC from your list), which is used rather frequently as a random attack sound, however it was removed from v1.0 onwards.
Now I'm not sure about levels 2 and 3, but level 4 in the beta certainly is very different from v1.0*. For starters, the dojo area apparently was supposed to be the boss battle arena (I haven't completed that level so I can't tell for sure), and the sign says "Dojo of the Sumo" instead of "Dojo of the Serpent", which might suggest that the sumo boss was in fact intended for the shareware episode. IIRC you start somewhere in the dark woods area and you're supposed to get inside the dojo building to proceed.
I also remember that level 3 is called "Temple of the Anime", but its general layout doesn't seem to have changed a lot compared to the beta version.
Level 2 - can't remember but the level name is also somehow different - starts you in a different location, already outside the collapsed tunnel. I think it might be the same location as one of the starting locations for the multiplayer mode (available with the -commbat# switch).
If I get around to play the beta more, I'll sure check what other differences there might be.

Nice to know you have such a rare historical version

BTW, do you perchance have the shareware CD version of SW? I wonder what version that release could be (CD audio issues are already mentioned in v1.0's SWHELP.EXE, but those could easily be leftovers from the registered Duke3D's help file).
*That is, unless I screwed something up and was actually loading levels in fake multiplayer mode; I played the beta quite a while ago, but now I think that maybe level 4 as I remember it was more or less similar to what you get if you load it in v1.0 and higher with the -commbat# switch.
