There's a lot of obsession with 'new games are better' amongst modern board gamers that they overlook what's good about the classics and why they are still here today.
I admit I was kind of the same way at first, plowing through hundreds of modern games and mostly ignoring older games, but if you take another look at the classics there's some real gems there. A few other excellent games you don't mention are Shogi (500 BP), Cribbage (420 BP), Fanorona (340 BP), Crokinole (150 BP), and Acquire (60 BP).
Although IMO, Double 6 dominoes is where it's at, not double 12. "All Fives" Dominoes and Partnership Dominoes are highly underrated amongst modern gamers, imo.
