I run boring, stable Debian on mine, but I have plentry of experience adding the non-free (not foss) drivers not included in the core distro. For gaming with lots of native hardware support right out of the gate, Bazzite is really popular.
No matter which distro you settle on, see if you can install the ‘linux-headers-generic’ package to avoid broadcom wifi issues after every kernel update.
Not quite the same actually; mine’s the mid-2012 MBP with a more generic Intel GPU. Yours is slightly better, but that Nvidia hardware is sometimes harder to drive properly on Linux. Bazzite should make that a breeze for you tho.
