NEITHER.
Over easy eggs should be prepared in a pan, not directly on the flatiron. This facilitates the turning of the eggs. The size of the pan should be just large enough to keep the eggs together without forming the combined whites into an unnatural perfect circle. If you are cooking directly on the flat top, sunny side up is the way to go. If the diner prefers a more thorough set to the yolk, steam it under a cloche… but it should still be an "up" egg, not an "over".
I am a fan of toast being fried in just butter, personally… but I think it would be safe to use a mix of butter and rendered beef fat. It would change the characteristic of the toast. The toast would adopt some of the fond and seasoning from the steak; this would be appropriate for a workingman's breakfast, but not for a king's breakfast.
If you're going to scoop baked beans onto the plate, none of these concerns matter, and SPAM may be readily substituted for the ribeye.
Since you may in fact be a SPAM eating type, remember to slice it square for sandwiches (the can's instructions may mention a "SPAMburger"), rectangular for non-sandwich breakfast applications (like served in lieu of bacon or sausage). When frying SPAM, it should be fried until a golden crust forms, but not so long that the crust becomes crisp. Frequent flipping can aid this goal.
