i have a question for any cfadmins out there. Can someone give me a little more detail info? I am running CF2021 Enterprise on Windows 2019 server. What is the purpose of the CF ODBC Server service?

as far as i know it's only relevant if you need any ODBC datasources to be used by CF. so, if you don't have any ODBC dsns defined you can turn off that service (unless things have changed dramatically with recent acf versions)
