This is the first I've heard of this.

Where in bitcoin core can I see info about the UTXO set?

You can use BTC RPC Explorer on your node with https://github.com/janoside/btc-rpc-explorer
or here public instance https://bitcoinexplorer.org/utxo-set
I think BTC RPC Explorer is a very underated tool for node runners.
or
The bitcoin listunspent rpc call does that
