Ah, the modern Gibson Les Paul...yes, there are a few questionable choices and design flaws but otherwise an extremely well built instrument with that iconic muscle car tone.
I'll second what DistortED says about the Faber bridge hardware. It helps unlock some extra clarity and sustain with a combination of steel and aluminum materials. Your whole instrument may resonate more and feel more "alive."
String Butler actually works and helps fix a 60 year old design flaw by keeping the strings uniform across the nut (like
Fender,
PRS). It will keep in tune much better. $40 and at the very least they are compatable with any stock aftermarket tuners with hex nuts. You may not even need locking tuners really, just lubricate the stock TUSQ nut they put on the 2021 models.
The stock Burstbucker 1 and 2 pickups are actually quite good, the problem is that Gibson has a bad habit of using 300k pots where 500k pots should really be the norm. Using 500k can increase clarity further and eliminate any muddy tones to be had.
Treble Bleeds on the volume pots - go-to values can be 500pf with 200k resistor in series. These make the pickups far more versatile and actually usable at lower volumes on guitar when you don't need full-on distortion all the time.
Then you can finally adjust your amps' treble and mid setting back down to earth and enjoy some proper tones.
If you are still not satisfied with the Burstbuckers after these changes, the last thing to consider would be magnet swaps - try Roughcast Alnico 5 or "Unoriented" UOA5 Alnico 5 - these add depth and 3D tone to the stock polished A5 or A2 magnets (depending on the year Gibson used either in their Burstbuckers).
You will then at least now have the best foundation to hear the full potential of any pickup swap. Consider virtually anything in the boutique aftermarket, it's all subjective.
