We're probably a little bit too early to be focusing on these things. Not sure if we actually need a symbol for every bitcoin denomination, but if we would, It'd probably make more sense to focus on bits and mbits first. We're probably a long way of seeing things priced in sats.
Anyway, someone proposed a symbol for sats on Reddit a year ago:

I agree there are more important stuffs to consider why waste time on thinking about Sat's Logo?Anyway, someone proposed a symbol for sats on Reddit a year ago:

And just like what you said I also think that there is no need to create a logo for Sats and even Bits people are already aware of the denomination of Bitcoin and newbies could easily search and compute it on the internet.
