What you have posted in the question makes sense. Small extension based on your own code:

import pandas.api.types as ptypes
my_columns = []
for col in df.columns:
  if ptypes.is_string_dtype(df[col]): 
    my_columns.append(tf.feature_column.categorical_column_with_hash_bucket(col, 
        hash_bucket_size= len(df[col].unique())))

  elif ptypes.is_numeric_dtype(df[col]): 
    my_columns.append(tf.feature_column.numeric_column(col))

  elif ptypes.is_categorical_dtype(df[col]): 
    my_columns.append(tf.feature_column.categorical_column(col, 
        hash_bucket_size= len(df[col].unique())))
