The options available to you are also generally not going to be nearly as lucrative as physician practice. Worth considering that, especially if you have loans.
Edit: If you really don’t like the prospect of being a clinical physician for decades until you retire, but you can stomach a few years of the work, grinding for FIRE is doable in most specialties. Spend as if you were making resident money, aggressively save the remainder, and take as many shifts as your physical and mental health can reasonably bear. Once you hit financial independence, you can scale back to however few shifts per month you want. Or you can just work in an entirely different field that may not pay as much but is enjoyable for you. Or you can just retire. The amount of time that will take will depend on your individual situation (debt, COL in your area, pay ceiling for your specialty, etc.), but I’d bet most physicians could manage, assuming they have the discipline.
