What kind of cms with flexible unloading yml file to choose?

A question, what kind of cms with flexible unloading yml file to choose? I understand ready-made solutions have NetCat and UMI.CMS. Will not be uploaded to Yandex.Market and various trading platforms that accept yml format. If someone experienced please help, I saw various additions to free cms but not sure is it sensible to build a shop\showcase based on free cms without technical support.

You can choose any cms, but the yml file create through a third party service, like ymlka.
To create the file in such service it is sufficient to enter the website address, it will do the rest myself.
In addition to creating, it will allow you to monitor changes on the website and periodically update unloading.
