For airliners generally VNAV manages your speed for you, but make sure you are at most 250kts below 10000 feet. Once you are close to the airport, if you are vectoring yourself, a good ballpark figure is 250kts at 15nm, 240 at 14nm, 230 at 13nm, and so on until you reach your approach speed. But most airliners will decelerate on their own, provided they are in VNAV/managed speed.
There are plenty of tutorials online that you can watch to see how they manage their speed. Not least are the ones in aerofly’s ‘tutorials page!
In airbus, if you activate the appr phase, yes the plane will slow down to approach speed if you extend the flaps.
On boeing aircraft, once you are on final approach, pilots typically manually select the speed and reduce it themselves.

Additionally, the Airbus usually knows when it is in the approach phase. On the fmc there’s the (DECEL) waypoint which decelerates the plane to its approach speed:)
