To contain everything....Then the dry lot could contain almost any livestock we might want to get.
I would vote for no climb woven fence, inexpensive metal wire electric strand at top, maybe at middle and bottom depending on the animals.
As far as posts.... eh, if you are going with woven no-climb... pick whatever you like best.
Maybe you want a temporary electric set up now.... and later put up a great no-climb fence.
