Newer frameworks like Svelte or SolidJS are a lot less bloated on the client. Though we're still far from successfully minimizing the amount of network roundtrips involved in a SPA update, so there's plenty of room for improvement still.
I like what Ruby on Rails 7 has done with Hotwire and Stimulus. All html is rendered server side. If you need client side interactions, you can mount lightweight components using plain JavaScript.
