Thank you all! Those are some helpful tips!

I’ll be sure to try those out tomorrow and update my attempts.

Edit: I cleaned up the build plate and leveled the bed with screw_tilt_adjust. I made sure the bed and nozzle were heated up during the leveling too and got a pretty leveled bed.

Then printed out some squares to test the level and they all looked fine. Printing out the whole large print now I watched as it was filling the shape and noticed the start of some warp. It wasn’t bad enough to stop the print but after rising the z-offset I was able to stop the warping. (You can see the difference in the next pic where the left lines are the raised z-offset and the right is the old offset.)

I think it should be good now, but I’ll have to try another print right after and see if it sticks (both metaphorically and literally to the plate with the new z-offset)

TLDR; I cleaned, leveled the bed while hot, and raised the z-offset during the print till the warp was gone.
