Thanks - I set Edge Cache TTL to 1 hour, then later 8 hours. This didn’t fix the issue, unfortuately. Still, the only file on our page that is cf-cache-status: DYNAMIC and not :HIT is the 1st call to the html page itself. According to webpagetest.org this adds about .9 seconds before TTFB (Time To First Byte). This will be much faster when we’re able to get Cloudflare to serve the file, not our origin server.
