I have two suggestions:

https://www.amazon.com/ILoveFidget-Spinner-spinner-detachable-bearing/dp/B06Y4JTRQS/

The first one is a nice spinner with a plastic body that has a pleasant whirr and that has some feedback (not too smooth). The second one is a classic (sometimes called cigreen C3). Depending on the bearing, the C3 might be fairly smooth, but then you could swap in another bearing to give it more feedback. They are both easily under three inches.

I could not figure out which Trainium spinner you were talking about. The one that I found on Amazon weighs 22 grams. What is the weight of the one that you bought that you say is too heavy? The WeFidget Bar is probably the one also known as the zenduo or the cigreen tank:

This is a classic, like the C3. I am surprised that you find it too smooth -- it usually has a nice amount of jutter. Here again, another bearing could increase the amount of feedback. FZ Essentials is the place many of us go to for bearings:
