Sending all 4 UTXOs together is the least private way to spend them since that would give a clue indicating the total amount you registered for that round, but it would not be fully effective since there are many input combinations that add up to that amount. Spending the private UTXOs individually or remixing them before sending your entire balance is the best way to handle them.

OK. Thank you. That's the way I understand it. But then consolidating 2 UTXOs in a coinjoin and getting 4 back isn't really consolidation, is it? The point of consolidation is to have fewer UTXOs after than before, because I want to save on fees when fees are high. No?

You can consolidate more than 2 inputs in each coinjoin round (up to 30 in BTCPay Server's implementation), but yes, you will receive multiple outputs to hide the amount.

Ah okay. That makes more sense. If I have 10 UTXOs I could consolidate them and then maybe get 5 out of it. Got it
