"Alternative A2DP Driver" offers this functionality on Windows. Lets you customize SBC parameters, use AAC, aptX (apparently, haven't tried). Works well in my experience, lets me use LDAC with my sony XM4's. It's trialware, but cheap.

I have seen the bluetooth range drop off in higher quality modes, which seems to confirm it's actually changing the codec (or at least something) and not just a placebo.

What is this "Quality Loss" they speak of regarding downsampling from 48KHz to 44.1KHz? When resampling is done properly, you'd only lose very high frequency content (frequencies above 22050Hz). Human hearing range is usually documented as up to 20KHz, but some young people can slightly hear higher frequencies.
