Question: I use Elementor / Beaver builder / Divi? Can I continue to use it with WordPress FSE?

Answer: Yes maybe. But WordPress core logic may be faster – there’s less to load.

Alex Shaw suggest using GeneratePress and Kadence WP with Kadence Blocks.

His favourite is Oxygen, which replaces all of the theme.

Oxygen is a lifetime licence.

with OxyExtras – load time as good as the Gutenberg block editor.
