Do such EMT pull elbows reduce wire fill rate as compared to regular 1/2" EMT

No. But they are limited as to the size of the conductors that you can install in them.

Assuming, no limitations then with 14 Awg? (12 wires). In reality I only need 6 or 7. Still, seemed tight

Not an issue if you can use stranded.. Solid is a bit more challenging.

I am trying to avoid mixing wiring. I need 6x 14AWG. Doable?

Is there a reason to not just use a box?

Sure.

Yes, but don't forget about derating. You can fit up to 9 #12s in 1/2" EMT.

Possibly no good reason not just using a box.

Here is a pic to illustrate.

I am using a light box on the other side of the wall to route them through.
Primary objective: provide power to kitchen ceiling lights and island range fan on dedicated circuit.

My constraints:
- there will be a kitchen cabinet close to wall. So, I like to stay within 1 1/2" total. (and yes, there will be a cover inside the cabinet that allows serving the elbow)
- I could have recessed a box and then route the emt inside the wall. But I didn't want to drill into 2x4 above.

Not sure.

I would have opted for an LB over the outside elbow.

 

[Eddie702]

LB would be slightly larger, but I agree with Larry probably a better choice.

4x4 box usually cost less and covers the hole in the wall as well.

I just had a thought (uh-oh): a plumbing escutcheon might fit the nose of an LB, or a reducing washer on the thread of the fitting/conduit if it's appropriate for the LB to be away from the wall a bit.

I've used reducing washer for that sort of thing before.
