Minimize cost 2. Maximize privacy 3. Minimize UTXO footprint You can build a coin selection algorithm that achieves 1 and 3, but will sacrifice 2. If you want coin selectin to maximize your privacy, it will happen at the expense of UTXO footprint and fees. Minimizing cost usually also minimizes UTXO footprint but not always. To completely minimize UTXO footprint, you sacrifice a bit on cost, and a lot on privacy.
