In addition to always just checking for loose screws and such, we've found it helpful to actually list specifics on our sheet- figure out which things are more likely to ever come loose, so we make sure they always get extra special attention!
We always check wires and connections, too, as well as clearances- if say a zip tie broke off and now a wire is hanging in the path where your rotating arm travels... just things like that. But checking for clearances could apply to a number of things anyway.
Then, Bumpers! Just to make sure we have the right color for the next match! And then this also helps us to keep track of matches when we check to see our next alliance, the times are right next to it if matches are still on schedule.
Most of the rest of our checklist is specific to our robot, but like some others have said, just restoring whatever needs to be restored, making sure hostbot and minibot batteries are fully charged (part of this check is to actually use a multimeter for us at least), and even making sure your driver station is ready to go, would all probably be beneficial.
Good luck!
