As a former ColdFusion developer, and not a hater of that platform, but given what you’ve said - I would opt to rewrite the app in a language that is more widely supported and builds on your strengths. ColdFusion 8 is super old too; no reason to support that or pay for an upgrade. As you mentioned Python and Flask, that’s a fine choice because the framework is lightweight and your needs are simple. One other suggestion for a basic CRUD app is to go with Node and Express, if you’re proficient in JavaScript.
