What should I check on a used M1 macbook?

Hello everyone!
I found a really good deal on a used m1 macbook pro (16gb ram, 1tb storage for 800 euros).
I'm going to pick it up on wednesday, what should I check on it? These are the things that I tought to check: visible damage, battery cycles, Icloud lock, keyboard. Is there something else that matters?
Thank you for your answers!

SSD writes, battery cycles, check to see if USB C ports feel loose. Overall check to see if device feels sturdy and see if screws on the bottom have any signs of tampering (if they look rounded etc).

 

These are what I used to check when I received company hardware back from users.

Thank you! Will definitely check those.
