Mapping Umbraco Form Data Types to default Umbraco Data Types

Questions

Is it possible to map Umbraco Forms data types into default Umbraco Data Types?

What I mean is something like this

foreach (var set in form.AllFieldSets)
        {
            var safeAlias = set.Caption.ToSafeAlias(shortStringHelper, true);
            if (type.PropertyGroups.SingleOrDefault(x => x.Alias == safeAlias) is null)
                type.AddPropertyGroup(safeAlias, set.Caption);

            foreach (var field in set.AllFields)
            {
                var dataType = dataTypeService.GetDataType(field.SOMETHING); // get the equivalent data type
                type.AddPropertyType(dataType);
            }
        }

In other words,

Get the equivalent Umbraco Datatype from a Form Field (data type) in order to add to a document type or member type.

Any suggestions or help will be much appreciated!

EDIT

I got as far as getting the details for the field using code from Umbraco Forms

    public static class FieldTypeExtensions
{
    public static bool TryGetFieldTypeForFieldId(Form form, Guid fieldId, IFieldTypeStorage fieldTypeStorage, out FieldType? fieldType)
    {
        Field field = form.AllFields.SingleOrDefault((Field x) => x.Id == fieldId);
        if (field is null)
        {
            fieldType = null;
            return false;
        }
        fieldType = fieldTypeStorage.GetFieldTypeByField(field);
        return fieldType is not null;
    }
}

But I still haven’t figured out how to map that field into a data type.
