Canon Powershot SX220HS to first DSLR

[Weslake-Monza]

Younger daughter may be taking GCSE Photography at school and currently has a Canon Powershot SX220 HS which she's had a couple of years. Either for a summer birthday or Christmas I am considering buying her a brand new DSLR. I'm considering a Pentax K50, Canon EOS 600D, 700D, 1200D and Nikon 5200D or 3200D. All of which I'd intend to buy with the 18-55 lens. At some point I'd buy her a zoom lens that is at least as long as what her existing Powershot zooms to (whatever x14 optical equates to). She tends to take a broad mixture of photos from close-ups of flowers to anything a long way away, such as birds,

Two questions:

Which camera of the above, or something different, will best suit her for the next 3 years and why?

What zoom lense size do I need to get that matches the Powershot (and what's the equivalent in 'old money' 35mm)?

Many thanks

Thanks for the interesting comments. No-one rates the Pentax with some s/h lenses?

Returning to this to ask a few more questions for myself, rather than for daughter this time:

Will the Nikon DX 40mm 2.8 Micro on a D3300 go in as close as my Olympus 35mm with a Zuiko 50mm MACRO lens? If not what would I need instead?

With the Nikon D3300 what lense do I need to match the Zuiko 21mm Super Wide, again uses on my Olympus 35mm.

Thanks
