How does a Bitcoin (Core) wallet use inputs?

When creating a new transaction, how does the Bitcoin Core wallet (or any other wallet) handle/use the outputs (UTXO's)?

e.g. when 2 outputs have to be used, will Bitcoin spend the highest address (most BTC) first and then the second highest or are the UTXO's used in another way?
