I usually run a width of .4 ~ .44, An have have always used the cheap brass nozzles without any troubles.
And hope we are both talking about PLA. I generally set my Nozzle to 196 ~ 202C and the bed temperature to 40 ~ 56C
1st layer no fan all others layers 50% fan speed.

Can you verify the Nozzle size by looking to see if it has an imprinted number on the nozzle. Some of my nozzles do and some not.

I have had them send me the wrong thermisters in the past. If you look and the Last picture in your 1st post.

You can see that the lines are spaced apart like you have a .4 nozzle and your slicers settings are set for .8 nozzle.
Then you have compensated and somehow got the CR3D.XYZ Benchy to somehow print.
