With so much changing in 2023 for elk in Utah (tag allocation changes, new hunt types, etc.) it is hard to say right now what it will look like in 2024. We should know a lot more through this 2023 application period.
If you are considering archery hunts only, you should be in good shape for bonus tags available on most hunts. If you were leaning early rifle, I think it is likely that there will be several units that won't have a NR bonus tag any longer starting this year now that only 10% of the rifle tags go to the early hunt.
You have set a very reasonable goal for an archery tag with a 320 bull and there are a bunch of units that can meet that, even as a DIY hunter in my opinion. If you are out of the running for the top 3 units (San Juan, Beaver, Boulder) based on your points, I would be looking hard at the Pahvant, Monroe, Mt. Dutton, Manti, Nebo, and maybe Fishlake or Wasatch.
You do have a lot of options for outfitters on those units, but some specialize in certain areas so narrowing down your unit choices would help with recommendations there. Shane Scott Outfitting guides on many of those units and would be a good one to check with to start out. Mossback (Doyle Moss) always kills some good bulls, as does David Virostko/North Rim Outfitters. I would NOT recommend Wade Lemon Hunting (WLH) but don't get me, or others here, started on that outfit
