I can't see anything about beacons in the description. Is there a way to use them, other than using custom blueprints?

No, the built-in layouts don't place beacons. Is there a problem with the custom blueprint layout when using blueprints with beacons?

Im not familiar with he custom blueprint option. Is there a library somewhere where someone has a beacon layout i can use?

You can design a blueprint yourself, for example something like this (using Krastorio 2 beacons in this case) with mining drill output going to the west. Do mind the numbers that have to be set up in the "Snap to grid options"

Then you just add it into the Blueprints layout.
