I covered that in the OP. It requires coding ability for anything other than a simple blog.

Thanks!

I covered that in the links in the OP. It’s extremely limited. I didn’t find it useful.

Redline the cheapest option until it catches fire.

It’s an important business website that would have severe consequences if it went down during traffic spikes (which it does get).

Why are you worried about your site going down during traffic surge? Unless you’re running a critical service, there is no need to worry about this too much if it’s just your personal sites.

With proper caching, your personal site can even tank traffics from reddit frontpage on a $5/mo vps.

Yeah, I’m using Cloudflare, and I saw that Wordpress has a built-in caching option, but I couldn’t find any info on how well that protects sites from traffic surges.

consider hosting it on platforms with autoscaling support such as netlify.

Yeah but I need an SSG with the same capabilities as Squarespace to do that, and as mentioned in the OP, that doesn’t seem to exist.

I’d recommend Statamic

I looked at the demo and it looks like a very simple text editor to make blogs.

Since you posted this into a self-hosting community…

I have two other websites hosted on a $5 Hetzner server (that counts as self-hosted right?). I’ve been considering adding a Wordpress, Grav, or static site to it. But as mentioned in the OP, I have to worry about the site going down if it gets a traffic surge, so I’m thinking it would be safer and similarly/more affordable to host a Wordpress site with Hostinger or GreenGeeks. Am I wrong?

Grab a Raspberry Pi, slap nginx proxy manager and ddclient into it, and point your domain to your home IP.

I’m not likely to do that, for multiple reasons.
