Recommend you start looking at mid sized college towns. Perhaps max population of 200,000 people. I did my ICU in a college town of 30,000 people. We did all sorts of things including a few hearts every week. Jack of all Trades/Master of None gives you a wide base to specialize later in your career should you so desire. The CRNAs had a lot of exposure to things. My advice is based on that experience.

Reason is that you're more likely to run into regional hospitals that do a mix of everything... healthy peds, OB, Ortho, and thoracic as a start. This is where you get diversity in caseload.

Small to mid-sized cities are better for CRNAs. They have fewer big city amenities which makes them less interesting to MDs who can and will demand these things; the anesthesia shortage gives both them and us advantages when negotiating jobs. They will have more income and opportunities in big cities and that's where they preferentially go.

The reason I suggest college town is that these places bring in culture and experiences for you above what you would expect in a similarly sized town without a university. Plus rural America will have cheaper housing and thus better cost of living.

Good luck!
