If I get off the plane at Hong Kong Airport at 7:30 pm, is it better to stay in a hotel in Hong Kong or take a bus to Shenzhen and stay in a hotel?

The area is not suitable for Zhongshan that night. The poster, you can choose the following methods:

(1) At the Panda Hotel or Far East Royal Hotel in Tsuen Wan, the two hotels are very close to each other and there are direct airport buses. I chose Tsuen Wan because it is relatively close to the airport. If you want to go shopping at night, you have to take the airport bus to Mong Kok or Tsim Sha Tsui and choose a hotel there. Then go to China Hong Kong City in Tsim Sha Tsui and take a boat back to Zhongshan the next day.

(2) Take the transit bus from the airport to Shenzhen Huanggang Port, and then transport the passengers back to Zhongshan the next day.

I personally would choose (1). After all, I have one night and one morning to visit Hong Kong and buy some things to go back to. Moreover, I don’t have to go to Shenzhen first after entering the country. It is also convenient to take a boat in China Hong Kong City.
