Requesting recommendations for a smart doorbell

My mom was interested in a smart doorbell to let her know what’s going on at the house when she’s not there, if a package gets dropped off or if someone tries to in. She does have a number of Google Pucks and an Android phone with some smart plugs set up with Google Home, but also has Roku TVs if that ecosystem is a major value add. I’m not super interested in yet another subscription service, but if it’s a “monthly fee to make the problem go away,” I can be convinced. Are there any must have recommendations or considerations I should keep in mind?

Edit: As far as I can tell, there’s no wire leads on or around the doorframe. The old setup had a chime wired to the wall of the foyer, but that was uninstalled and the wall was repaired, so I don’t think there’s a lead if that changes recommendations.
