Which Tablet Should I Get? I Need a Dummies Guide

So I'm a complete dummy when it comes to this stuff! I'm afraid despite owning a Samsung phone, a Samsung watch, and Samsung buds - I know absolutely nothing about the tablets at all haha. So, I need guidance as well as advice!

I'm a big laptop user - be that to surf the web, make Word documents, download movies, and so on. However, I've decided I'm going to move with the times, and get a tablet - especially as my brother has tempted me.

However, I don't know which one would be for me! I had a look at the S10, but it's very pricey - but if that's what suits me best, I'd go for it. Personally, I'm looking a tablet that'd also have a keyboard, so I could still work on my documents. However, I'm just looking a usual tablet for the other stuff. Which one is best for me?

Thanks
