You've got to lower your expectations, or prepare to spend more.
If you tell me, I just want to take landscapes. That's easy, certain camera or lenses will do that.
If you tell me, I just want to take birds photos. That's easy, certain cameras or lenses will do that.
If you tell me. I want to photograph my wife. That's easy, certain cameras or lenses will do that.
If you tell me you want to do all those? You either put up the money to get quality gear that can do all of them, or don't have the money and get low end quality from all of them.
You get what you pay for, if there is a camera can do all of it for £300, I wouldn't need £2,000 lens that doesn't even come with a body. If you want the best, you have to pay for it.
Compacts have their place and use, they are good when used within their capabilities and you got to know what those are and make full use of it. You can easily do that snowdonia photo with a RX100.
