What is the ruling on the groom opening the car door for the bride and holding her arm when entering the house on the wedding day?

For a husband to place his hand on his wife's arm and lead her into the house, there is no harm in it, as it is a permissible touch or enjoyment according to Sharia. However, the prevailing custom of the people must be observed in this regard. If it is something that people of honor and decency commonly do, then there is no objection to it. Otherwise, it is better to avoid it.
