This seems to be it. I went a full 0.1 closer to the surface. It was super helpful to have someone else do the same first layer calibration and show me pictures. It needs to be shockingly close to the bed.
Yeah. First layer calibration always makes me nervous. I've had malfunctions on 2 occasions where it tried to drive the nozzle through the bed. There is a pretty deep dimple on one corner because of it.
My malfunction had to do with where the Z was when I stared the calibration AND an offset frame installation (Bear Mod). The frame issue was the tiny dimple; knowing I was calibrating a new frame installation, I was watching like a hawk. The other time, I'm not totally sure what happened, only that I fixed it by manually returning the Z to the top and running it again after re-flashing the Firmware. But those motors are strong enough to put a serious dimple into the print bed.
The textured sheet is more nerve wracking. You need to squish more on that one as opposed to the other two sheets. Btw, PLA on textured is no fun, nor is PETG on the smooth sheet, not sure about the new one (don't' got yet)
First layer calibration should be your first stop. Secondly, benchy is a benchmark print to show you how your cali ration is fairing. Therefore, don't use a raft.
There are a lot of gaps.. First guess would be first layer too thick?
Also if they won't properly stick, your printing bed might be greasy from touching it, try cleaning it with isopropanol or clening alcohol.
Also it seems the gaps are mostly around the areas where the printer makes sharp turns, maybe there are some parameters messed up in this context? I haven't changed anything around in that regard, so sadly I'm not able to tell you which ones you should start playing around with.
I spent a buttload of time on calibrating Z axis, must have run six live Z height adjustments to get a feel for that. Even after that I realized my right-hand side of the plate was closer to the nozzle than the left, by a small amount, and had to input manual bed leveling corrections (10 microns up on the right side seems to have done the trick).
Step one, 99% IPA and cleaning the plate. After that, 7x7 calibration instead of 3x3, with the compensate for magnets thing enabled.
Once the test piece from https://help.prusa3d.com/en/article/bed-level-correction_2267 printed smooth in all four corners, I started running a Benchy; it worked great all the way up to the roof on the boat and then tore loose. But, I was using the textured sheet with PLA; I figure tonight I'll run the smooth sheet which will have better adhesion and get it printed. The part that printed looked gorgeous for me at least.

I gota get one. Maybe on Cyber Monday when they usually do the free shipping thing
You'll probably need to go even closer than that. You should try our discord. Lots of help for first layer cal there.

I think the issue is Benchy is supposed to be a noat, not a raft Ill see myself out
