You should change your coin selection to random, otherwise it currently defaults to selecting your largest utxos. The default is terrible for privacy and will grind your utxos to dust overtime.

Except when your node has to CPFP anchors or stage 1 sweep htlcs. Carrying an extra input utxo (or 5) at 200 s/vB because it didn’t select a utxo big enough is pretty painful.
IMO, if privacy is the goal, avoid using the hot wallet altogether.

You only need like 10-20k sats to bump, if you have utxos smaller than that, that is probably a problem

Here’s 2 examples from FCs from a few hours ago.
This CPFP needed 2 utxo, where the 2nd was big enough to go solo had it used largest selection - https://mempool.space/tx/d46cedf4e5b85dfde09b4ee4cfb713214e0956a6d6c932caf39195f0faa9bb65
Here is a 6 utxo CPFP (maybe they didn’t have a utxo large enough) - https://mempool.space/tx/039ae9e76659454b59412fb6cc63e22dfe621f967d22e424a953d8984430f1da
