How to open .cfg and .tex files with different applications on macOS?

Question

Every time I try to change the default application to open .cfg files, all .tex files are automatically set to be opened with the same application, and vice-versa. This is problematic since I would like to open .cfg files with TextEdit and .tex files with Texpad. Is there a way to do this ?

I don't know what causes this behavior, here's what I already tried:

Set various editors as default app using the standard method (File > Get Info > Open With > Change All). I tried with TextEdit, Textmate, Atom, Texpad on both types of files.
Set default app using duti.

Edit ~/Library/Preferences/com.apple.LaunchServices/com.apple.launchservices.secure.plist to manually add entries then restart, as suggested here. The entries I edited are the following:

{  LSHandlers = (
   ...
     {  LSHandlerContentType = "com.vallettaventures.texpadm.tex";
        LSHandlerPreferredVersions = { LSHandlerRoleAll = "-"; };
        LSHandlerRoleAll = "com.vallettaventures.texpad";
     },
     {  LSHandlerContentTag = "cfg";
        LSHandlerContentTagClass = "public.filename-extension";
        LSHandlerPreferredVersions = { LSHandlerRoleAll = "-"; };
        LSHandlerRoleAll = "com.apple.textedit";
     },
   ...
   );
}

Unfortunately, none of these approaches have worked.

System: I am running macOS 11.3.1 on an Intel MacBook Air.
