There's a bunch of different calibration prints that can help see how your printer does and tune it for your filament. Go to thingiverse and just search calibration. Each of them has something they help you tweak ... but that being said also dont be afraid to just load up some small models and try to print them. Some people get so caught up in benchmarks they rarely enjoy their printer (Think people that just mod and do dyno after dyno but never actually race their vehicle kind of thing).
I'd join one of the creality or ender groups and see if someone has a profile made for the printer, they are often much better than the factory profiles that are poorly tuned.
