In which situations should we use Cypress or Robot Framework? Are both good choices to get tenured manual testers into the practice of automating their work for tests of APIs and functional tests of web applications? Cypress looks great for functional testing of web applications and Robot Framework looks great for everything else.

Background: We have over a thousand functional test cases for our web applications being executed manually by a QA team. Our front ends interface with APIs written in Java with various frameworks over the years (e.g. Spring, Spring Boot, Java EE). I think our testers could learn enough of the basic coding in JS, Java, and Python required to automate most of those cases.
