Respectfully if you can’t afford the $5 you shouldn’t be wasting dev time on a POC. And further you are signaling to cloudflare that you would be a terrible customer.
If I were them I’d raise the price tier.

But for "let's play with this serverless stuff and maybe use it for something real in the future", $0 AWS lambda wins over $60/y Cloudflare workers. Or for hobby projects, doing it traditionally and running it on the $60/y VPS I already have instead of spending the money. And if asked later, CF is going to be the one I can't give a direct assessment of.
I would suggest to those that have the skills to make use of cloudflare workers that there are more straightforward ways to change that problem than building proof of concepts against them.
Also, if the currency is of lower value, they get paid more. Example being the English pound is of a higher denomination than a dollar, but whether it's "worth more" is dictated by purchasing power, relative movement over time, etc.
If you have to pay $5 for Cloudflare Workers, $5 for some more page rules, $13 for your (light usage) Postgres instance, $7.50 for your t3.micro, you're already at $30/mo baseline and you're not close to high availability.
