The SSG hack isn't really viable after testing it. Non-cached requests to a cold start app are still insanely slow, like 18 seconds:

18s!!! :O I haven't seen a cold start over 2s!
Yeah, doesn't seem right. Guessing it's either because I'm not paying enough money yet or I have too many deps. (I'm in the process of removing redux everywhere but not there yet).
At this point I'm dropping SSR almost everywhere, running a next export and trying to cover as many getStaticPaths as I can, while relying on /api routes continuing to be served by Cloud Functions.
Maybe some day I'll migrate to Cloud Run, just don't have bandwidth atm.

Makes sense! I'm going to look more into Cloud Run when I get a chance. Looking forward to your blog post.
