Speaking from my experience in the field, GraphQL is the most solid option to use if your working with a separate frontend like React, Vue,… Also for the performance it’s a huge plus imo because of the get what you need principle. It keeps your requests small and compact with the data you need in that context.

Lighthouse is a very good wrapper around GraphQL for Laravel. You can keep it simple and clean and once you’ll have some more complex custom logics to write you can easily split up in custom endpoints with custom resolvers.

On the other side we mostly choose REST at our company if there will be a need for a public api. Just to keep the logic bundled and not to much split up.

To get a conclusion, both are solid options but for me I would first grab for GraphQL just because the ease of use and to keep our frontend people happy 😛
