Any position other than on your back is beneficial to you- AND improves the baby's ability to negotiate your pelvis. Being on your back in the usual delivery position increases your chances of tearing. It also prevents your pelvis from opening fully and makes it more difficult for your baby to drop under the pubic bone to get out. Any other position will prevent those problems (squatting is associated with a slight increase in first degree (minor) tears but a HUGE decrease in 3rd and 4th degree (major) tears).
Evidence-based practice says that continuous fetal monitoring increases your risk of a c-section but does not reduce risks or improve outcomes. You can request intermittent auscultation which means that every 30 minutes in first stage labor and every 15 minutes in second stage labor the nurse or your care provider will listen to baby's heartrate with a handheld doppler or the fetal monitor before, during, and after a contraction. Fetal monitors were actually never tested- just mass marketed by the company that developed them.
Water birth is beneficial to mom and baby- it reduces pain, tearing, and unnecessary interventions. It provides a warm transition for baby as well.
I would highly recommend a midwife over an OB. Midwives provide more hands on care- you can expect your midwife to sit with you the entire time you are in labor while a doctor will just come at the end to catch the baby.
