Why placard says 80 and Goodyear says 65
The placard and n my 312bhts says run the Good Year Endurance tires at 80 psi. But the weight/ pressure table on Goodyear’s site says 70 psi for 3000 lbs which would be right for a 11,500 lb trailer (max geoss) with 4 tires. So. Why does GD recommend 80? Seems a softer ride might be enjoyed at 70 or 75.

You will not have equal loading on all of the tires. The 80 PSI should hopefully cover this difference in weight on each tire. The other way around this is to load the trailer for camping and have a company come and weigh each tire. Then you will know for sure what pressure to inflate to.

Don't try to turn tire pressure into rocket science. Inflate tires to the max recommended cold pressure as indicated on the tire. The manufacturer accounts for increased pressure when running.
This will give you maximum rubber on the ground, the least sidewall flexing, coolest running, and the greatest longevity.2010 Jayco 26(SOLD)

I use the load inflation chart with a cushion, for example if you 2 axles carried 10K lbs I would choose a PSI to handle at least 3K lbs per tire. I have the endurance tires on my current TT and 65PSI would be fine but I run 70PSI for a little margin.
The max pressure on a tire is max, not recommended. Over inflating for the load could result in less road contact and faster ware in the center.
Most trailers seem to recommend max PSI, probably because most manufactures provide the minimum tire capacity they can so max is the proper pressure in that case. Not sure why GD would do that here unless it is just force of habit.2021 Imagine 2800BH

If you plan on going by weight, then you'll have to find a scale that can weight each tires individually. It's not necessarily trailer divided by 4. The side with your kitchen, fridge... will be heavier then the side with the dinette and couch. I just go by what the sticker on the tt says.
