Minimal overhead, I suppose, is an 'extra feature' that I want. This is why I'm currently using DietPi OS. It's basically PiOS Lite with a few pre-enabled performance features...

It's likely that I will stick with DietPi, or at least PiOS Lite, for this exact reason. Probably, I will switch to PiOS Lite, though, since it has a
64-bit build, while DietPi is 32-bit only.
I'm certainly not refusing to try other Linux flavours, but I prefer Debian due to familiarity. I will look into a couple of other flavours that have been suggested, particularly Slackware. I may just transfer PiBBS to my PC while I play around with OSes on the Pi for a while...
