Welcome to the forum.
Judging from the couple of items you have mentioned an SE lux from 2011 onwards is probably the way to go, the standard spec for them is quite impressive and includes, Electric rear doors and tailgate (remote open and close included), panoramic roof, full leather with heated and electric front seats, folding mirrors, 3 zone climate and more.
If you are looking for one with extras I can recommend the bi-xenon lights and the heated windscreen, as both are fab additions to have. I also have self park on mine but I think I have only used it twice in 18 months, and that was just to show people how it worked. Its a must if you are not confident parking a large vehicle but other wise its just a bit gimmicky.
