To get the advantage during the point, you have to either take away time from your opponent or open up space (and then take advantage of the open space). Hard body serves, hitting with a lot of pace, hitting deep returns right at the opponent are all examples of taking away time which can force short balls or errors. Serving wide, returning deep to corners, returning with short angles, drop shots, short slice angles, hitting deep to a corner, short/angled topspin to take an opponent off the court, hitting close to the sidelines etc. are all examples where you open up space and then can take advantage by hitting into the open space with the next shot.
If you hit deep to the corners, deep body serves, deep DTM on returns or deep groundstrokes with more pace than an opponent can easily handle, then it is a good strategy. Serve-and-volleyers hit deep down the middle and approach the net sometimes as it reduces the angles for passing shots - approaching deep to the corners is good too if you slice low or hit a high topspin ball. If an opponent cannot handle your heavy topspin, hitting deep and high to the weaker wing (usually BH) can be a good, repeatable strategy too.
If you just hit mediocre pace/spin shots deep in the middle of the court and don’t have a strategy to take advantage of it later in the point, it might not be a good idea against a consistent opponent with good shot tolerance - might be better to make them run laterally or up/down.
