If you are playing 5e and in 5 years nobody has been using shove I would be honestly really surprised and I would like to see how your fights run including environment (out of curiosity, not critique).
I used it to throw enemies of heights (pushing 5ft, not 20), my barbarian is using it regulary (waiting for his chance to become battlemaster to make it part of an attack with tripping maneuver) as first attack to knock enemies prone to get adantage for his 2 attack and bonus action attack if there are also other party members that will have their turn before the enemy can stand up - or in cases going reckless might not be appropriate... I use it to help party members disengage (either pushing the enemy or them), I use it to get enemies into darkness or fog (or out of it).... but that's how I run encounters and I tend to run them quite demanding (rule of thumb CR = sum of all party members levels).
Shove in 5e is very, very valuable even without the buffs it gets from Larian.
