In VueJS, where specifically do you typically look to catch emitted events?

Let's set the stage:

export default Vue.extend({
 name: 'Home',
 computed: {
   ...mapState('user', ['card']),
 },
 created() {
  this.fetchData();
 },
 mounted() {
  this.$once('dataLoaded', () => {
    if (!this.card) {
      this.showWarning();
    }
  });
},
watch: {
  '$route': 'fetchData'
},
methods: {
  async fetchData() {
    await Promise.all([...]);
    this.$emit('dataLoaded');
  },
  showWarning() {
    // Vue global Plugin for creating a banner
    Notify.create();
  }
 }
});

I placed the listener in the mounted lifecycle, but I'm contemplating whether it should be in the created() lifecycle instead. It seems to function properly in both instances, so I'm curious if there are any best practices I should follow or if I overlooked something crucial here.

Appreciate your insights!

Stop making things more complicated than they need to be. You don't need to use emit since you're only dealing with one component.
Just follow this approach:

methods: {
  async getData() {
    await Promise.all([...]);
    this.customMethod()
  },
  customMethod() {
    if (!this.card) {
      this.displayAlert();
    }
  }
