Let's see what the pricing calculator says. Assuming you stored 1GB of content, with 4MB images, and you transferred out 40GB of content each month:

  1 GB per month / 0.00390625 GB average item size = 256.00 unrounded number of objects
  1 GB x 0.0230000000 USD = 0.02 USD
  100,000 GET requests in a month x 0.0000004 USD per request = 0.04 USD (S3 Standard GET requests cost)
  40 GB x 0.0007 USD = 0.028 USD (S3 select returned cost)
  0.023 USD + 0.04 USD + 0.028 USD = 0.09 USD (Total S3 Standard Storage, data requests, S3 select cost)
  Internet: 40 GB x 0.09 USD per GB = 3.60 USD
  
  Total: $3.69

And for 1TB stored & transferred & 1M GETs each month:

  1,024 GB per month / 0.00390625 GB average item size = 262,144.00 unrounded number of objects
  1024 GB x 0.0230000000 USD = 23.55 USD
  1,000,000 GET requests in a month x 0.0000004 USD per request = 0.40 USD (S3 Standard GET requests cost)
  1,024 GB x 0.0007 USD = 0.7168 USD (S3 select returned cost)
  23.552 USD + 0.40 USD + 0.7168 USD = 24.67 USD (Total S3 Standard Storage, data requests, S3 select cost)
  262,144 number of objects x 0.000005 USD = 1.31072 USD (Cost for PUT, COPY, POST requests for initial data)
  Internet: 1024 GB x 0.09 USD per GB = 92.16 USD
  
  Total: $118.14

Assuming Cloudflare had a significant cache hit rate, you'd save a decent chunk of change.
