you sound like you know your meat.pause but no pun intended
what cuts do you like the best?
Ribeye is my go to. At minimum, you'll usually get good marbling. You can run into the occasional steak that has too much fat in the middle, or weren't trimmed well, but your odds are lower of having that happen at a good steakhouse, or higher quality cuts at the store.
Also, you're probably more likely to find grass-fed/finished or dry aged ribeyes at the store than you are other cuts, just based off popularity, and usually the steak is good enough that you've got plenty of options on how you want to cook it.
