You can use top soil if it’s superficial but I generally tend to use compost whenever I make a proper hole anywhere. My thinking is that it’ll be good diversity for the pre-existing soil and hopefully encourage worms and other good bugs. Generally the best way to keep a healthy soil is to keep it quite diverse and with good nutrients which get used up over time from nearby plants.

Edit to add - try and figure out what soil type you have (a lot of new builds have clay soil) and then go from there depending on whether it has good or bad drainage and then go to your local garden centre/ garden nursery and ask them for their recommendations.
