Congratulations on finishing your residency. My cousin went for his cardio surgical specialty and something like 7 years of residency.
For what you described, turnkey can work. Any form of investment RE ownership will help offset passive income. Max out any employer retirement plan if you work for a system. If you started your own practice, get a self-directed retirement plan and max that out. There are several providers around or contact me if you need a referral (I don't get anything for it). This will help reduce your taxable earned income, but there are legal methods to use IRA money to invest in RE. If you haven't seen a tax bill at your higher income bracket, you might want to get a colleague prescribe something first (joking).
The warning: Any kind of "hands-off" approach will require you to diligently monitor the operator. That means every month, but not less than once a quarter, you must set aside the time to review your agent's activities and assess what is going on, then determine if all is well or if you need to get involved. For busy professionals it is easy to say you will get to it later, but later becomes next year. Before you know it, your investment is lost when a minor correction could have changed its course.
To effectively monitor your investment, you must understand it. Doesn't mean you must be the expert. You should be able to rely on others, but you should be able to recognize the difference between when the transaction is going off the rails v. when it is experiencing a systemic correction affecting all assets in the same class.
Finally, let me re-emphasize: you do not need to be the expert. MDs and JDs suffer from the same condition: we tend to be the one everyone looks to for guidance. After long enough time, that mindset spills over into areas we have not been trained to lead. Sure, lots of times we will be in the top percentile when it comes to intelligence, but that doesn't mean we always know better outside our bailiwick.
Besides turnkey, you can create a "turnkey" system. Buy new-ish properties (wholesale, not retail) with conventional financing and hire a trusted property management company. That is a buy/hold method. If you can find TRUSTED flippers, you can "partner" with them to convert small capital into larger capital capacity. This also kills your tax bill, btw.
Until you get over the $50K threshold, there are few "hands off" investments in REI. Once there, syndications become an option. I understand that's not ideal, but it is passive. Another is to work with a legit hard money lender or REI debt fund. Both are backed by real property, decent returns (possibly) without driving up your tax bill too much, and leverages you into bigger/more SFR. Or if you do it long enough, builds your down payment for commercial (without needing to syndicate the deal) when you are ready.
Good luck.
