Check this thing out.
Here it is: https://www.amazon.com/gp/product/B004SH40BQ
There's a picture of it in an iPod Nano on that page also. It stuck out about an inch or so? Maybe less? It wasn't too bad.
I'm using a KOKKIA i10s with my iPod Classic 7G and AirPods. It costs $60, but its really worth it! https://www.amazon.com/KOKKIA-i10s-Black-Bluetooth-Transmitter/dp/B004SH40BQ/ref=sr_1_3?ie=UTF8&qid=1538599448&sr=8-3 Works with my bluetooth speaker as well.
As annoying as the floppy dongle would be, the 3.5mm solution is the most reliable one out there.
There are some models that, while they still stick out like a sore thumb, try to keep the package as compact as possible. Here’s one: https://www.amazon.com/gp/aw/d/B00IQYC4R4/ref=psdcmw_9926003011_t1_B01KXIKCSI

I bought this one and it seems to work good so far (other than the issue with AirPod volume range mentioned in OP):

Use the 30-pin instead of the remote port but they work.
No bluetooth on that iPod? Get something like this (that one's way way way too expensive)
