Should I create a page rule for a 500kb .htm file?

General Rules
1

I didn’t know that Cloudflare does not cache HTML by default.
The main file of my website (main.htm) is 500Kb. Should I pass it through the cache? Sometimes I have 1000 visitors online.
Is this rule correct? I’ve used it but I don’t notice a difference.

If that page does not change with user logins, etc., then it’s safe to cache with a Cache Level of “Everything”, and you’ll need to set Edge Cache TTL to something low (whatever the minimum TTL is on your plan).

What’s the difference between “Standard” and “Cache Everything” if I just want to pass “main.htm” through the cache?
Thanks for answering.

So I should select “Cache Everything” for a single file? (main.htm)
Is the screenshot correct?
