Tips for first time laptop owner

I have bought a Lenovo LOQ 15 15AHP9, and it should be delivered soon. Any insights on what to do first when getting it? I know about general one's like updating drivers, bios, removing bloatware, maybe even fresh install? I have seen posts about repasting too, maybe I need to buy special brushes for cleaning laptop? I live in Lithuania, the weather here is mixed if that helps and here are the specs:

15.6" 1920 x 1080 @ 144HZ, AMD Ryzen 5 8645HS, 4.3GHz, 16GB DDR5, 1TB SSD, RTX 4060 8GB
