A smart doorbell makes sense if you actually take advantage of the features. If it's just to see who's ringing, honestly, a regular doorbell already does that. Now, if you want to get notifications on your phone when someone rings, record videos of people coming to the door, or integrate it with other smart devices, then it's worth it.
About brands: the imported ones (like Ring, Logitech) tend to be more stable with better apps, but they cost a lot. National ones like Positivo Smart are cheaper and work perfectly fine here if you have decent Wi-Fi coverage. The cost of "dealing with Wi-Fi" itself is zero - it's just connecting to the network you already have. What really matters is having the router reasonably close to the door or with decent signal there; if the signal is weak, the doorbell gets slow or loses connection, and that's frustrating.
My suggestion: before buying, test the Wi-Fi signal at your apartment door with your phone. If it's good, go ahead; if it's weak, it won't work well regardless of the brand. And check out specific reviews for the brand you're thinking about - they vary a lot in reliability.
