Mine never fills up all the way. Shuts off early and then spills out bottom if I try to top it off

Sounds like a shitty pump.

I seem to remember that on one of my very first fill ups, I didn't quite get it to a full tank. No issues since then.

I think the key is to get the nozzle all the way in at the start of fueling, barring any mechanical issues with the filler tube or nozzle sensor.

Most of our pumps around here don't lock. They also have shitty rubber diverter flaps that keep you from putting it in all the way, or so it seems.

I've come across 2 pumps at 2 separate stations that have overfilled me (both Chevron). I've just stopped using those, and so far, no further issues.

Zero problems. Learned how to fill up a car a few decades ago and never forgot

The problem is in the EVAP/purge system. I would start with #11, the fill limit vent valve. There are other possibilities, such as restrictions in the vapor tube (#4) or problems in the canister itself (#3). But this is a venting problem in the car, not a gas pump problem, IMHO. Insects have been known to get into these lines at times.

Fill Limit Vent Valve
This acts as a shut off valve during refueling. This will vary based on fuel tank design. The fuel limit vent
valve has the following functions:
The fuel limit vent valve is located on the inside top of the fuel tank
This valve is not serviced separately
Controls the fuel tank fill level by closing the primary vent from the fuel tank and forcing the fuel fill
nozzle to shut off.
Prevents liquid fuel from exiting the fuel tank via the EVAP pipe to the canister.
Provides fuel-spillage protection in the event of a vehicle rollover by closing the vapor path from
the tank to the EVAP canister

DESCRIPTION AND OPERATION > FUEL SYSTEM DESCRIPTION (FUEL PUMP
POWER CONTROL MODULE) > FUEL TANK
The fuel tank stores the fuel supply. The fuel tank is located in the rear of the vehicle. The fuel tank is
held in place by 2 metal straps that attach to the frame. The fuel tank is molded from high-density
polyethylene.
The fuel tank is a saddle configuration in order to provide space for a driveshaft through the center area
of the fuel tank. Because of the saddle shape of the tank, two fuel tank fuel pump modules are required.
Mounted inside the fuel tank, as part of the tank assembly is a fuel limit vent valve that is designed to
close the fuel tank vent when the fuel level reaches a calibrated level during fueling. When the fuel limit
vent valve is closed the tank pressure increases during the filling process. This increase in tank
pressure causes the filling station fuel pump nozzle to turn OFF. When the fuel limit vent valve is opened
fuel vapors in the fuel tank are allowed to vent through the fuel limit vent valve and hose to the EVAP
canister.
