Consolidate by using a coinjoin/mixing service. Samourai's whirlpool has been my go-to for years now. Sometimes I forget and leave them remixing for months, then take them out, one UTXO at a time. That way you end up with nice large, privacy-protected UTXOs to hodl onto.

Try to keep the UTXOs as large as possible (based on the pool choices), but it's also a good idea to a have a few smaller ones - The more diverse the better, it's about striking that balance between number of UTXOs and how large the UTXOs are - Even smaller UTXOs are useful after all and may be preferred to larger ones even in high-fee scenarios.
