Depending on the size of each UTXO, I would keep them between 1 million and 10 million sats.

If you consolidate them all into a single UTXO, then you run the risk of compromising your privacy/security later when you send and unknowingly create a specific type of address cluster called peeling chain. https://www.whatisbitcoin.com/learn/what-is-an-address-cluster

Also, I if you decide to consolidate them into more than 1 single UTXO, I would consolidate them into a new address(es) 22, 23, 24, etc… in your wallet.

If you want to get real experimental with consolidation, you can consolidate with a CoinJoin to make it more difficult for CA companies to follow the money on-chain.
