The OB is the least of your concerns.
The person that you need to influence is the L&D nurse. The nurse will monitor your labour and steadfastly follow hospital procedures, and recommend your epidural. When you are fully dilated, she will page the doctor who will arrive in time to catch the baby.
You really do need to have a written birth plan. Anything that deviates from the norm should be sanctioned by the college of Obstetricians and Gynecologists.
It will be very difficult to decline an IV. You may be able to compromise on just having the cannula fitted, but no line.
You should be able to stay mobile, even with an IV.
You should be able to have intermittent monitoring, but they will probably insist you are fitted with a belt.
You need to agree limited VEs with the OB and make sure it is on your notes.
Pain relief is basically epidural or nothing. If you want nothing, you have to make sure you can get into whatever position you want, and are not subjected to time limits.
If you want to see what is typical, watch a few episodes of 'A Baby Story". If you don't like what you see, make sure it's on your birth plan.
Take your own food for after the birth, especially tea bags. And take paracetamol too.
