There's at least one not cloudflare company doing this, though I think I forget their name. It might be yunohost.org, they definitely do provide mastodon hosting, but there might have been one that focused more specifically on hosting fediverse instances. I've heard testimonials for them saying they take the sysadmin work out of running instances, but I suspect most of these people already have some technical background so it's hard to say how helpful it really is.

I don't think it's really that important to have a highly streamlined deployment process, mostly because I don't really see the value in single-user or micro instances, but that's a matter of preference
