From personal experience
Employers will almost always give you free time off for a CME-about a week but you have to be doing stuff for the CME. You don't do CMEs? You don't get the time off. From most places I've seen, most will not pay for it.
If they do agree to pay for it and it's a state job, and you go to a nice place (e.g. Hawaii or a cruise), don't be surprised to be on the front page of the local paper being called the new gold-digger of the community. I've seen several colleagues have this happen to them. In Cincinnati, a local pathologist with the coroner's office went on a CME, and the local paper tried to make it as if the state was paying for this doctor to have a free vacation, showing the nice highly rated resort hotel the doctor stayed at.
Insurance? Several places will pay for your insurance. Despite this, careful. I've seen several cases where the employer claimed they will pay but when the person got sued, the employer used every dirty trick in the book to not pay for it. A good friend of mine was a victim of this. He was sued, and when it went to court he had to pay for his own lawyer at a cost of several thousands of dollars when the employer was supposed to pay for it.
Where I'm at now, I know from several colleagues they will very defensively guard their doctors. A friend of mine with the department was sued and the legal fees were $300K and the department paid for all of it without burdening my friend at all.
The general recommendation I've heard from many is even if your insurance is covered by them, get your own anyways as backup.
Board exam fees? No. I've seen no one ever pay for these.
Relocation? 50-50. Some yes some no.
