I'd go for scribing. The job isn't the most fun (you're typing on a computer for nearly the entire shift if you're in a busy facility- which is most ERs and clinics!), but you do learn a lot just from doing the charts. A LOT. And that part is pretty interesting.
You generally get to see:
1. The complaint that the patients have and all their symptoms
2. Their relevant medical history to their current complaints
3. The results from the physical exam the Doctor does (usually get to be present for this too)
4. What labs/imaging/interventions the Doctor orders and the results of these tests/interventions
5. The doctor's final thoughts on how they determined what the issue was, what they did, and any further care/treatment the patient may need in the future
The amount of actual care (e.g. suturing, putting a chest tube, etc) you see varies depending on the situation. Most care is provided by the doctor and the nurse without you present (you have a lot of charting to do!), except in emergency cases (stabilization cases off an ambulance where the patient history/charting is done simultaneously with the care being provided). I've found most Doctors are more than happy to let you come in if you've never seen a chest tube put in before, sutures, or a reduction (among numerous other procedures).
The doctors don't dumb anything down for you doing their charts either. You'll learn so much medical terminology. A patient isn't breathing fast, they are tachypneic. They expect you to use this terminology in the charts.
I've also found most doctors are willing to take time to explain things to you if you don't understand something. Why did this lab value make you believe this? Why did you order an MRI for this headache patient when you haven't for the last 40 headaches I've seen with you?
Another thing is you start to see things that doctors do that you dislike and things you really like. One doctor I work with always just walks up to his patients after introducing himself and while the patient is still talking starts his physical exam, often with palpations of what ever part is hurting. It tends to startle the patients. Fantastic doctor other than that, but has taught me that a quick "I'm just going to start examining your stomach, tell me if anything hurts" would go a long way in helping to not startle a patient and make them more comfortable.
I've altogether been surprised at how nice the doctors are to us and how much I've learned. I've shadowed in an ER before becoming a scribe, and while shadowing taught me a lot about a doctor's daily routine and how their day works, I've learned way more about medicine from scribing.
