Good morning,
Intuitively it is obvious that a laptop should be more expensive than a desktop, but if you don't care much about spec in practice laptops seem to be cheaper! More in sales, on special offer etc.
I switched to a laptop with external keyboard, mouse and monitor for main day to day use in the late 1990s, altough I still bought desktops for server use and see why power users would still do so.
Given that you don't seem to need anything powerful, the only warnings are be cautious of very cheap laptops as;
If your current machine is pre Win 10 you may be shocked how poor Win 10/11 are with a spinning hard disc. SSDs are now essential, just how we got this position is another topic !
Really cheap laptops may come with tiny 128GB SSDs which are very easy to fill up.
Everything is memory hungry and even your modest needs would be 8GB
CPUs are expensive and the really cheap laptops may be have skimped a bit too much in this area,they won't be a disaster but they may be irritating.
Argos have this for

Also lookup Windows S mode, it is designed for non enthusiasts but comes with issues or not depending on who you are.
