The question you asked is really important and I think there are person that don't care much about privacy.The mixing tools you made mention of like whirlpool, joinmarket and wasabi are still being used by many but the most important is the method of usage or how we utilise then .despite how active and sharp Blockchain surveillance maybe, if we still know how to make use of this tool it will really help alot.So the tools you mention are very good if we know how to use them.Also I do make use of samourai, stonewall and I do avoid combining UTXOS.Infact it is important to use multiple tools.
You are absolutely right. how we use privacy tools is key to their effectiveness. It is great you are using tools Samourai and Stonewall and that you are smart about things like not mixing your UTXOs. Even with advanced tracking on blockchain knowing how to properly use these tools and even using several of them together can still give you much of privacy by making it much harder to trace your funds.
