I’ve been very happy with Ubiquiti’s Unifi Protect doorbell. It does mean having to buy into their whole ecosystem, but I was already most of the way there when I added the doorbell and a couple 4k cameras.
Recording to a local device does mean you have to consider things like power/network outages if you want remote access and recording to continue during those events. I’ve got all my network gear and the doorbell transformer running off a UPS to cover the time between a power outage and my whole-home generator kicking in. I’ve also got an LTE modem to fail over to on my Dream Machine Pro (Router/network controller/video storage).
