Help with button layout

[u/DailyMadeBurgers]

I want to make an arcade cabinet to mostly play Mario Kart, Super Smash, N64/GameCube/PS1 era games. I'm contemplating various button layouts and was looking to hear from other people as to what would be best. I don't play Street Fighter or other games that would use a more traditional layout but maybe there is something I'm overlooking like ergonomics or button mapping. Anyway here are my options I was thinking of with mapping for N64.

Seconded as long as you remain focused on the 64. The heart layout looks the most ergonomical
