NFTs that implement IERC721Enumerable interface are easy, you can call tokenOfOwnerByIndex for each index 0 to (balanceOf() - 1). For NFTs that don't implement that interface or have a similar function, you will have to rely on querying transfer events and aggregating those, or seeing if they have a subgraph or similar service to fetch tokenIDs per address.

ALternatively, it can sometimes be feasible to iterate the whole collection and call ownerOf() for each token, aggregate that way.

yeah that's the simplest way for most people. You'd just query all collection transfer events from/to the account (starting at whatever block the contract was deployed, typically). Easy enough to then aggregate what their holdings are now based on what tokens came in and out of their wallet over time

depends on if you prefer web3.js or ethers.js... They both have good documentation on how to do it. Here's ethers.js section on querying events: https://docs.ethers.io/v5/single-page/#/v5/api/contract/contract/-%23-Contract--events
