The only VERY basic, simple, non tech advice I can give is, if you take lots of photos, get an S rather than an A model.
I had an S10 - pretty old - and took literally 1000s of photos with it. Then 'upgraded' to an A14 (on the advice of a 'salesperson') and the photo quality was noticeably poorer.
So, I've gone back to my old S10 and am currently saving for an S-something newer.
The salesperson conned you there!
The A70 I got shared some of the same tech as the S series, I think I read the camera was the same sensor just the app behind it was not as fully tricked out as the S. It was described in reviews (widely not just one source) that it was close to the S series in performance. In fact the A7x series was ended after the A71 I think because there was not enough differentiation in their range. They had cheap (A0x) mid (A3x and A5x) then high (Sxx). The A7x was from what I read taking some sales from the S series so was dropped. When I got my A70 (within the first month of release in the UK) it cost me something like £370 whereas I think the S10 came out that year for £800 I think. The A50 I think back then cost only just below the A70. It certainly was good for a number of years.
