I've had the opportunity to train junior developers on React, Vue, Svelte, Solid, and even Angular. And I've used Ember professionally.

The objective time-to-profficiency has made React (and Solid which is quite similar to React) the most obvious choice for us, and I'm one uncomfortable with consensus. Svelte doesn't quite have the staying power of React or Vue yet. Since it's a superset of JavaScript, it's harder to teach, and the component frameworks just aren't there yet. Vue is great, but Vue 3 took a step towards performance and a step away from intuitive readability IMO- it's probably better suited to a team with homogeneously high experience.
