If I find access to my wallet, I want to use Coinjoin because I don't want the recipient of my transaction to know the original balance of my wallet.
Than you should think about using Silent Payment addresses in future.
Cake wallet is one of the first wallet to support them, but there are others working on them like Blue wallet, Wasabi, Bitbox hardware wallet, etc.
Since I haven't been involved with Bitcoin for a long time, I have no idea about the current technical circumstances, but I came across an article reporting that Arkham Intelligence has developed algorithms and patterns to completely deanonymize transactions, even Coinjoins.
They obviously can't track everything, but user making mistakes with bad address management is making it easier.
Don't expect to have perfect privacy using Bitcoin, even with coinjoin or joinmarket, monero is much better for that purpose.
