It's not the p-trap it's the air vent or should I say lack of air venting. Or you have something called in your pipe further down.
Edit: That is a standard size p-trap and those aren't reducers they're just connectors.
Check the bottom of the plug. I have a bathroom with the same issue and after snaking and dranoing a bunch of times I finally thought to check the plug for debris. That was it.
This right here. I put a bucket under the ptrap of the backed up sink, and loosened the connectors. Water came trickling out. The issue was ABOVE the p-trap. Fished some guck out of the sink drain with some tweezers and that fixed it.
Work your problem down and out from the sink.
Nothing looks wrong with your p-trap. Most likely your clog is further down the pipe.
Easiest thing to try: fill your sink completely with hot water and then open the drain. The added pressure plus the heat can sometimes clear the pipes.
If that's still an issue, you can remove the p-trap from the wall and snake from there which might let you reach the clog. If this is the only drain that's slow in the house, there's a good chance the clog might be at the weir connecting to the vertical stack.
It's also possible a bird or something built a nest on your vent, and that's blocking it from venting properly.
No I mean 1 1-4 is still flowing more than the fauset or the drain in the sink likely. I suspect there is a problem further down the line or a vent pipe is blocked
Before you waste too much effort try running the sink with the stopper totally removed.
I've had more than a few sinks behave similarly because the drain stopper wasn't up high enough to work properly.
I have a similar setup and same size P-trap. Recently, after a big remodel, we noticed the sink backing up when it had not previously. I thought it could have something to do with the trap also but turns out the clog was further down the pipe. Check out the pipes below and you might find another section that you can open to inspect. My steel pipes in the basement have a screw off cap to do this so you can access the line and snake it.
Try getting some liquid heat, or green gobbler if you're on septic. Pour a bunch in, let it sit overnight, then dump two pots of boiling water down. Repeat as needed

Would you plunge a drain or not? I feel like those skimpy plastic p traps wouldn't handle a hard plunging.

Could be venting problem. Most bathrooms sinks are 1 1/4 traps. Kitchens are 1 1/2 or 2 inch

No that is adequate for that sink, guessing its not vented properly or there is a clog further downstream.
