I have exactly the same setup. But if I install lighter feeling strings I raise action indeed by about .25 to avoid buzz. I don’t think bass needs a shim for such adjustment, at least not mine. It’s a very personal setting, I just go as low as I can without introducing buzz past 15th fret. It might buzz slightly unplugged but as long as I don’t hear it amplified - I don’t care.
I also check slap/pop, sometimes having action set too low makes slapping weird, as strings don’t have enough back and forth travel for slap to sound good.
In my case with shim non-tapered strings have less bend less at the saddles, because shimming also raises string anchor point, not only screw height, and sinking screws reduces the angle at the saddle peak.
Without shimming non-tapered strings look like literal ^ at the saddles, splitting the wraps a bit and exposing the innards at witness point, depending on string construction.
