Launching a product is only 20% of the stuff. To take it through the product lifecycle, taking time to collect more perspectives, on ground research etc can be super leveraged over each quarterly/annual updates.
As a junior PM with execution as the main KRA to learn, I get your concern. You will keep getting the core product execution stuff to work, spread over the years, but the critical and hard to get skills like building a product sense, understanding evey need at a 10000ft level of org view, building a longer thesis etc - these get built with the more you observe, learn, understand other functions in the org and so. These later skills is what's gonna differentiatae you at higher role levels.
Also as one other comment here said - getting a shot at owning the PnL, like a GM can be a thing which sets you apart down the years.
Use the down time to do market and competitor research, show intiative and energy to your heads and eventually you will reap some benefits.
