4 years-old Golden Retriever goes nuts when we received guests at home

TD;DR; A 4-year-old Golden Retriever gets very excited when we have guests at home. This behavior only occurs in our house and not outside.

Hello there, I am not a regular writer here, but I am a senior reader, and this subreddit has helped me a lot in the past.

I am coming here to ask for your help to understand the underlying issue with my dog, and how I can properly properly on it.

Generally, I don't have issues with him. He is very well-behaved and has demonstrated this in various situations outside our home.

He is very social, and we often visit crowded places and events, such as restaurants, bars, fairs, markets, stores, and gatherings, without any incidents. I frequently take him to my office, where he behaves like the good boy he is. He may bark once or twice a week when he needs something, but overall, he is the calmest dog I have ever had.

He is a gentle soul to all living beings he encounters, including dogs, cats, toddlers, squirrels, and birds. However, he is somewhat afraid of larger dogs and prefers to avoid interacting with them.

However, as it is said in the title, my golden goes crazy (in a friendly manner) when we receive guests. He only behaves this way at home, whether with new or familiar guests. He demands attention, barks, and humps. When we visit the same guests at their house, he remains calm and does not act the same way as he does in our home.

As a side note: we receive different guests around 1 or 2 times per month. Intercom also calls his attention, but not to this level of craziness.

I have the impression that he is anxious about something: laboured breathing, excessive barking, jumping, and a non-stopping tail.

If I attempt to lower his excitement levels by commanding him to go to his place or bed, sit, or lie down, he will start barking and whining, ultimately breaking his place command. The same happens with crating, but he eventually settles after about 20 minutes of nonstop barking and whining. Once he is settled, if we release him, he will go crazy again.

Food works for a while, but it is noticeable that he is very anxious while eating it. We also tried raw cow femur since it lasts longer than regular treats, but he quickly loses interest.

We also tried to tire him before we receiving guests, but his energy levels does not affect how he behaves.

I appreciate any suggestions and guidance on how I can address this situation. I am happy to clarify any question.
