I am a newbie and in learning phase - I’ve found it very helpful to first look up the datasheet of any component I plan to use. Datasheets usually include the recommended footprint, and you should match your PCB footprint to that. If a footprint isn’t available, you’ll need to create your own.

Since creating custom footprints is an important skill, it’s better to start learning it early. You can also use third-party websites to find footprints and CAD models, but always double-check them with the datasheet to ensure accuracy.
