You should really use official shipment numbers for games that have that. It's not the exact same as sales ofc, but realistically it's a lot closer to the actual sales than the VGC estimates, especially since they stopped updating those.
Also you should decide whether you're going with all exclusives or just 1st parties. You state here you'll be including games made inhouse or contracted, but I'm pretty sure Persona 5 was neither for example.
Yes I'll go hunt for shipment numbers, but that will take a little more time.
On the Zelda and other similar complains it was crossgen, but on the next thread it won't be an issue.
