The sweet spot for RAM speed is 3733 MHz or 3600 MHz. Beyond that, performance actually goes down as the Infinity Fabric clock will get cut in half so anything higher than 3733/3600 MHz is pointless.
Yes, highly dependent on the IMC of each chip too. Some can run higher than others but most are 3600/3733.

Indeed running faster RAM is not always making the system faster but it's not totally pointless if one is targeting specific needs like binning high speed RAM. You can't even do that on most earlier Ryzens.
