Only thing Wasabi 2.0 does is ask third party chainanal tx some info (score) about UTXO when registering it into coinjoin and in worst case will just refuse to mix specific coin (but you can still spend it without coinjoin). But it does not do anything to cluster UTXOs in your wallet together.

JoinMarket doesn't do neither of these. It can't ban UTXOs by design (no single centralized coordinator) and doesn't reqest any blockchain status from third parties. But it requires you to run full node.
