Google Cloud Run (with Dockerfiles) + CloudSQL (Postgres) + Cloud Tasks. On the back-end, NestJS with Typescript plus some query builder such as Knex (TypeORM is pretty buggy). Or maybe even try Prisma. For front-end it depends. I would try using just Vanilla JS with Tailwind if possible or fallback to React + Tailwind if there are too many screens, or they need a lot of updates based on state. Those are mostly technologies I'm comfortable with because I use them every day. However, if I have the option to waste time researching and/or learning, I would research the state of server-side Kotlin and learn Elixir/Phoenix before making a decision. NestJS can ge too verbose sometimes.
