Re: digital cameras
You have a few options - I'm gonna patronise you a bit by neglecting the technical jargon.
You can get a DSLR (a camera with interchangable lenses) or a compact camera (has one lens you can't remove).
I have both. DSLRs have a huge price range - you'd want to get her a decent cheap one - Canon, Nikon, Fuji all good brands. Get her a kit lens that allows her to zoom in and will be a cheaper price point. These cameras are technically better but obvs all the lenses aren't free - she might never buy a second lens if she's not serious about photography.
The best compact cameras on the market (IMO) are the fujifilm X100 series. I got a fujifilm x100F a year ago for 800, mint condition but 2nd hand. It's super easy to use, creates fantastic clear images, has wifi so you can get pics on your phone or laptop without a cable, and most importantly, is small and lightweight so you can take it everywhere. You could get one for 750 now but remember you need to pay for memory cards, perhaps a strap, case etc. This produces images that are almost as good as my full frame mirrorless camera which cost thousands, and is much nicer to use.
If you live in Brum, Wex Photo Video on Hagley rd is a great shop with super friendly staff. They give you good advice and don't pressure you into buying anything. I'd go there for better tips.
If you buy second hand, look beyond physical condition to ask about the shutter counts. Cameras generally have a life of about 250k actuations I think and it costs a fair bit to get the camera shutter replaced.
In your budget you can definitely get her everything she'll need. If she's new to photography it's more important for her to get a camera she can use and learn from than getting her a high high spec thing she's scared to break.
A pro tip, for whatever you buy, is to get her a lens filter. they are about £25 and are clear hardened pieces of glass that go over the actual lens. They don't impact your images in any way, they can help protect from the sun's glare, and they mean you don't worry about scratching the lens.
