You are spoilt for choice!
All of your options are interesting. I would probably get the females if not too small, as I would like to see interactions with the males even if not with the intention of rearing fry.
I am not sure about another dwarf cichlid, I would be worried it may be aggressive with the Dicrossus, especially Ivanacara (from what I have read, zero experience with them). Or the Dicrossus might not accept another cichlid? I don’t think Nannacara fits the biotope quite well.
I like the tetras options, especially the ones we mentioned yesterday, and, as suggested by RasmusW, the ruby tetras - they are small and pretty and definitely a blackwater species. H. sweglesi are nice but a bit bigger and not so strictly blackwater though that might not matter., they may be less delicate than the others.
The Poecilocharax looks interesting. For some reason I was reading about it the other day, maybe someone else mentioned it, not sure.
Why don’t you want otos by the way, is it based on ethics as so many die in transit? Which is sad I agree, but they are small and interesting and don’t cause any trouble…
Well, whatever you decide will be good I am sure. Keep us posted…
