Don't consolidate UTXO'S unless they come from the same source. I used to think this was smart, and it does save you on fees. Its just that linking all your previous transactions together is not worth it IMO.

A better way is to use lightning by swapping each of those small UTXO's into a larger LN channel. Then swap out larger sized UTXO'S and refill.

For swaps you can use robosats, boltz or diamond hands. Some mobile LN wallets have swap functions in the wallet itself (phoenix or electrum).
