I use both smart bulbs (ikea zigbee) and smart switches (shelly) together.
If you combine them with something like the adaptive lighting addon in home assistant then you can have the bulbs adjust brightness and color temperature depending on the time of day, while still keeping the original wall switch.
As for places like IKEA, they prefer smart bulbs since replacing lightbulbs is something any average Joe can do(so they sell more), whereas playing with switches generally requires an electrician.
