Platform engineering tools

Good chances I will be tasked with implementing a service catalog - we have a recently formed platform engineering team. I’m not sure what I think of this (I was actually planning to move into something else in the org), and will be either asked to implement a microservice catalog (think backstage) or full internal developer portal, like port or configure8.

What tools has your organization used and why? How long did the set-up take and what did you like or dislike?
