Hi, welcome to the forum. Glad you joined.
This type of question is fairly common on here. Unfortunately it is an essay type question, not true-false and you usually wind up with many more questions than answers.
What do you consider a good meat bird? What traits are you after? For many people size is hugely important, not so much for others. How do you feel about ratio of dark meat to light? The way you want to cook them can have a big impact on what age you need to butcher them. Some of us like an early maturing bird as opposed to one that takes longer to mature. Are you only eating the boys or will you eat the girls too? Will you be buying everything they eat or will they forage for a lot of their food? If you are buying all their feed you might want one with a good feed to meat conversion ratio. Are you planning on plucking them or skinning? If you pluck a light colored bird will give a prettier carcass than the a darker bird. Your Ayam Cemani/Olive Egger mix might have really dark, even black meat. Would that be a problem? There are other traits that some of us find important. Some of these might point you more toward a Cornish X or Ranger type than a dual purpose. You'll find all kinds of different ways we go about that on here.
Of your breeds and crosses.
I'd go with the Dominique rooster. All his offspring will be barred, no big deal, but with most hens they will also be black. If you pluck that may be an issue. Dominique were developed to be a dual purpose chicken and should suit you. Polish are often bantams so they will not have much meat on them just form size. Their body conformation may not be very meaty either, more bones than meat.
Orpington/Wyandotte hen - Should work well. Both are good dual purpose breeds.
2 Sumatra- Whatever the sexes thee are more ornamental than for meat. Their body conformation is not for meat and form what I have read they are pretty small.
2 Speckled Sussex- Another good dual purpose breed. Sussex are pretty popular for meat in the UK.
A red/brown pullet and Olive Egger - If they are about the size of your Orp/Wyandotte or Sussex hens either should work well. That's your judgment call, you are looking at them.
Ayam Cemani/Olive Egger- Would black meat cause a problem, might not be appetizing? And the Ayam Cemani are typically pretty small chickens. Again your judgment but I would not have much hopes.
These suggestions are based on what I'd consider a good dual purpose meat bird. It may not suit you ate all. This is the point where I suggest you try it and see how it suits you. If you don't like it eat the results and use that knowledge gained to better plan that next round. If you have questions, ask away.
