For your purposes stay away from the Chromebooks. You won't be able to load the Microsoft suite of programs on it. They get great battery life, but have very little storage and weak chips. They're great for doing email and searching the web, but that's about it. I have one, it's great to travel with but not for anything like working on my pictures. I have to wait to do that until I get home.
You will have to work with word programs like Google Docs, the same goes for spread sheets - all of it is stored in the cloud and you don't have decent access at home to use those.
When buying a new computer be sure to find out what programs it comes with. If if doesn't come with MS Word and Excel, you'll have to pay more for those. Right now on Amazon they range from $200 - $300 And if a sales person tells you that it does come with them, make sure they're not just a temporary demo load that will stop working in a couple of months until you pay for them.
Also check on removable / exchangeable batteries. Very few if any laptops have that feature anymore.
Also, I don't think you want to mess with Windows 10. Now everyone don't get your panties in a wad over that comment - I'm saying that being somewhat familiar with Mex, that I don't think he want's to mess with WIN10 so he needs to make sure what he's buying before he gets a surprise and no one to help him when he gets home.
It is interesting what comes up if you type CHEAP LAPTOP into Amazon.
