Partial answer - I have the Anycubic Kobra S1 and use the Anycubic slicer - which is based on Orca also. I just downloaded Obscura's image album of settings and then went through mine to manually create my own profiles. I've been super pleased with it. You should be just fine to use the Elegoo Slice

I do For new users, Elegoo Slicer is easier than custom setting up Orca or other slicers from my experience. You don't have to use Elegoo's Slicer but the defaults are great for getting a user in the ballpark to print. Once a user has more experience, they may consider trying some of the other slice

Most of the advice here is sound, though may seem a little brief.It does look like you have Z-offset issues on this print, but also that the printbed is not level.
