It shouldn't be that slow. Did you enable Jetpack caching and such?
WordPress sites can be lightning fast if cached well. I forget what the WordPress.com options are, but if you host on Pantheon, Wpengine or similar, it can be very very fast.
You can also self-host on Cloudways (managed WordPress containers), now owned by DigitalOcean, or use Gridpane to deploy it to any VPS with a dashboard.

(Disclaimer: I work for one) Headless CMSes can often do this, but usually you have to bring your own frontend. Astro makes this setup pretty easy to maintain (it all works together and is maintained by a single vendor). Of course Next would work too but it's much more complicated. You'd still have to manage the frontend though :(
There might be a static generation plug in for WordPress too. I can't remember exactly.
