What softwares do i need to download AFTER i build my pc?

I'm Building my first pc tomorrow morning and I have very little PC knowledge, and have used mac and apple products all my life, so I'm not used to these things. My specs are:

Zotac RTX 4070 Super TWIN OC

Ryzen 7 7800x3d

Thermaltake king assassin 120 see ARGB

Kingston fury ddr5 32gb 6000mhz cl36

Kingston KC3000 2TB

Corsair 850W

Gigabyte BG50 AORUS ELITE AX ICE

I need to know quite literally EVERYTHING I NEED to download after I'm done, from RGB software to "drivers" which I don't really understand, because I thought when u buy the products they come with up to date software. I also want to know what software will make sure my PC is running fine without having to pay anything. I think this was called benchmarking. Also, my friends dad told me that I might get some free games depending on what parts I bought, but there was not really any promotion on the parts, so how would I check this? Also need to know literally all software that have anything to do with my parts specifically, as well as all the nvidia software I need to get. Thanks so much everyone and remember this is my first build, so even if it seems obvious, please mention it below.
