As for the units deer and elk season don't overlap there. Lots of the good bucks that come out of 32 during general season are from private ground, not saying that you couldn't find one during general season, but most of the unit is winter range for deer and elk. If you draw the late season tag for deer in the unit your odds increase a lot.
32A is split up between desert(sagebrush) and timber. Most of the desert country is private ground, so that leaves you in the timber which is mostly forest service. There is a good chance you can pull a good buck or bull out of this unit during general season, but it would take a lot of scouting, also general deer and elk don't overlap.
From the initial units you listed, for general season 43 would be a good choice. For draw tags, any of the units in the Owyhee's, 45, and 22 are good choices.
