Video Doorbell S330

I got the Eufy S330. It has an additional downwards pointing package camera and can connect to the existing doorbell wiring for power and to use the chime. You'll just have to make sure the doorbell transformer is the right size. It's an easy swap if it isn't. The big thing I liked about Eufy is that it isn't cloud hosted and there's no subscription. Just buy the hardware and be done with it. https://www.amazon.com/dp/B09QFK3JWS?ref=ppx_pop_mob_ap_share

Eufy familock. Doorbell and lock in one. It’s excellent

Eufy is the way to go

330 is the older doorbell and includes a the older hub. A lot of the smart features are not supported by that hub, so the 330 needed a faster SOC. The 340 is the newer doorbell that moves a lot of the smart features to the newer hub. As a result the 340 has a slower SOC and more limited features when used without the hub. With a hub they are pretty comparable, by the local smarts on the 330 can help in some cases. 

I've just started like you, also in the UK Ive gone for Eufy S330 doorbell, Eufy S3 pro cameras. They're great. No wiring, battery/solar power, night vision on the cameras is unreal I've got an Eufy X10 Omni pro vacuum and again, can't fault it I've just setup my home assistant, and found community integrations for all of them. The robot vacuum is pretty complicated but doable if you take your time.

I just swapped my eufy S330 for an Aqara G400 and holy crap it is just so much better. I miss the dual cameras but the instant video feed and having the video come up on my Apple TVs is a huge improvement. I had previously ported the Eufy doorbell to HomeKit through homebridge but it never worked well. TLDR: love the G400.
