A Thames river cruise can mean five quite different things in London, and the price runs from about £10 to £119 depending on which one you pick. The cheapest regular fare is on the Uber Boat by Thames Clippers, a fast commuter boat you pay for by tapping a contactless card. Then there are the sightseeing boats with a crew member doing live commentary, lunch, afternoon tea and dinner cruises, speedboats that race out to the Thames Barrier, and in summer, slow boats upriver to Kew and Hampton Court. Most of them share the same stretch of river through the middle of the city, past Parliament, the London Eye, St Paul's, the Tower and Tower Bridge.
My short answer: for a first visit, take a sightseeing boat from Westminster to Greenwich with Thames River Sightseeing (£17.20 one way, £22.50 return), spend the afternoon in Greenwich, and come back on the Uber Boat. If you only want the view and the ride, skip the commentary and tap onto the Uber Boat for £13.70. Book a speedboat if you have teenagers. Skip the dinner cruise unless the occasion matters more than the food.

The piers are all near a Tube (the subway) or DLR station, and most of this page starts at Westminster Pier, right outside Westminster station. You can pay for the Uber Boat and the Tube with the same contactless card, and London has no tourist tax yet. For the rest of your trip, the best things to do in London has the full list, the best day trips from London covers Hampton Court and Windsor by train, and if a cruise is really an excuse for scones, the best afternoon teas in London are on dry land and mostly better.
