You probably have to buy the books to read a lot of it, but maybe there's a torrent somewhere. You can see a few images here, some are only partial strips or covers or whatever, it's just a representative sample of sazae-san through the years, but it will give you an idea before you commit to a book,

I wouldn't recommend it for beginners. It's handwritten, inclined to puns, and because it's in comic strip format there's often not a lot of context. If you can already comfortably read your average slice-of-life serialized manga without furigana, then sazae-san could be fun. That's probably more what most people would call 'upper-intermediate'.

I haven't read Doraemon but I've heard that it's a good choice.
