If you're looking for a quick way to verify those files without running a full restoration test every single time, you can usually run a checksum comparison (MD5 or SHA256) against the original data.
For a more 'point and click' approach to double-check specific files or verify hashes quickly, I've used https://thetoolapp.com/utilities/file-integrity-checker/ before. It’s pretty handy for a quick integrity check if you aren't in the mood to mess around with the command line for every single backup set.
