Don't sweat such things. None of them are anymore than a starting point for a new filament. Every printer is a rule unto itself for best results with any given filament. And most filament brands put a sticker on the spool to tell you what temp ranges the extruder and heat bed generally work best with that brand.
So pick a starting temperature for the nozzle and bed and then print a temp tower or two if you really want the best out of the filament with your particular printer. Then adjust accordingly and save YOUR profile. If it doesn't matter much, those mid-range temps will work just fine. And no extra thought required.
I know that,but for the rarer non PLA/PETG stuff you only print once in a few weeks it's sometimes handy - and I kind of "preach" 3D printing to non-technical,often older, people sometimes, and they are often "not that sure what they are doing" yet, so that helps a lot.
And on the stickers things like density, flow, etc. are mostly not noted.
The slicer assumes those settings built in. And will take care of those finer details well enough for those "older non-technical" people. Each slicer assumes density and flow rates for each filament type that will work good enough for the vast majority of people. Just make sure your new people understand the importance of selecting the correct filament type and to choose a temperature for the nozzle and heatbed somewhere in middle of that sticker on the spool. At that point, 95%+ of all problems will be solved for them.
As I said, each printer is a rule unto itself. So your desire for settings for every brand and type of filament won't make anymore difference than is already built into a slicer. And settings like flow and density can and do change from batch to batch and even spool to spool. And it can quickly become a game of whack-a-mole, (I got a tee shirt somewhere around here). And if you are printing expensive engineering filaments, I would really recommend you go to the manufacturer's website and look up their recommendations for those materials. This is why I buy MatterHacker when I need those types of filaments. They have data sheets for each filament they produce. While I'm not much concerned about common PLA and PETG, I don't trust any filament retailer that does not have those data sheets for expensive engineering filaments. Nor should anyone else.
Your slicer should have generic profiles for each material which should give acceptable results with most brands. Density and flow tend to by the same across brands for any given material, unless it's a "rapid/high flow" or foaming filament, in which case the manufacturer prints the recommended settings on the spool. Basically if it's not printed on the spool you can use just the defaults in your slicer.
Yeah. I am sure there are some corner cases where a different brand of filament might benefit from different settings but that is going to be nothing compared to your printer (e.g. heated printbed or not?).
