What are the best duty stations for a 68W? What training options are there that are beneficial to making the most out of the MOS?

You won't get your choice of first duty station, but you can reenlist later for a choice. Ask for airborne training.. Study A&P it's the key to understanding medicine.

Each time I've been told to make a "wish list" I have gotten home of the places I put on it! Could end up anywhere really you just have to seek out opportunities.

I might be a little biased but once you have been in for a bit definitely look at flight medic. It is the best job I've ever had, even though I really like it when I dont have to do my job. Just focus right now on BCT/AIT though.

I got 10th Mountain as my first Duty station. Pretty good chance of getting deployed if you were there years ago. Now...I don't know what the needs of the military and where they are sending units. It depends on what you want to do after the military.
If you can get deployment, clinic, and hospital training then you'll be doing well. I've taken A&P 1 and 2 with labs 3x over the course of 68W and civilian education. A Medic is a EMT-B in the civilian world. Most places aren't using or hiring Basic EMTs as Intermediate and Paramedics are worth investing in.
Military experience only transfers over so much. If you get out and want to work as an EMT, you can but you'll have to look into local and state requirements to see if there is anything else.
Likely, your first enlistment you'll have to finish before getting more options.
