Thank you, that is actually helpful. It raises a privacy concern that I had not considered before. I had considered backwards looking privacy issues, but not forwards looking. If I have a UTXO of any meaningful amount in the future and make a transaction, the recipient can see the change and know to some extent how much bitcoin I have, right? Therefore it may be prudent to have UTXOs of a decent size for cost savings but not large enough to reveal meaningful holdings.
I think you could solve it in the following way: Try to imagine what kind of transactions you will do in the future? For example, lets say you have 10 BTC total. I dont think there is any problem to consolidate your UTXOs, each containing 1 BTC. Most of your future transactions will probably not exceed 1 BTC in value. This means that when you use one UTXO, you will not immediately expose your entire stash, and on the other hand, you still enjoy the benefits of low transaction fees. If you have to spend more than 1 BTC at once, I dont think you will have a problem with a slightly higher transaction fee.
So, in short, I would recommend dividing your total stash into tenths and using only one of those UTXOs for small transactions.
