How do I list the canister’s account balances?

See this answer:

How to send ICP from one account to another using motoko?

The dfx command to check the ICP balance is dfx ledger balance <account id> (maybe with --network ic). To figure out the account identifier, use dfx ledger account-id to produce the identifier. Use dfx ledger account-id --help to see how to use the command. dfx wallet balance shows you the (cycles) balance of your cycles wallet.

For your other question, you can also find the answers in that thread in one of the earlier posts.
