I've been laptop shopping lately too. The market has changed since I bought my last one a few years ago.
If you are using Windows PCs, you probably want to buy a Windows laptop. If you buy a Windows laptop now, it will most likely be Windows 10, unless you can find a business-class or workstation-class laptop with Windows 7 Professional, still being sold into corporate markets not ready to upgrade (and at premium prices).
Your laptop needs to be capable of doing what you are now doing on your home PC. If you are doing more than browsing the web, you should be looking at similar memory, storage, processor performance, and a display adequate for your vision. When I bought a laptop as desktop replacement (Windows 7 era) I bought a Dell Inspiron 17 with a dual-core hyperthreading i5 processor, 500 GB storage. Same resolution (1600x900) on a 15-inch screen was too small for my old eyes, though my 40-something children do OK at 15 inches. A bonus on 17-inch laptop is almost full-size keyboard with numeric keypad. Some 15-inch will have either/or: if they add the numeric keypad, keyboards have to be smaller. Ultimately you get used to whatever keyboard you are using, size differences an issue only when using more than one, really a pain at three different sizes.
The laptop failed for two tasks: photo cataloging and processing, and flight simulation. It was adequate for video processing, and all my Internet tasks. For the photoprocessing, the screen was too limited with respect color gamut and viewing angles, and the storage was really too small. For flight simulation, the laptop was OK for Flight Simulator 2004 (except for keyboard mapping issues) but the Intel HD Graphics were a total flop on Flight Simulator X (and would be so for almost any games with 3D graphics). Both of these issues can be taken care of with two different kinds of laptops, premium models for the video, gaming laptops for 3d graphics games. I bought an enthusiast-grade desktop ($2000 with 22 inch monitor) for the two tasks the laptop didn't handle. A Windows 7 security upgrade killed the system drive on this one, it has since been replaced by an iMac for my photographic work and I am looking at a rebuild for the flight simulator work.
Chromebook is a web access tool, it runs a Linux-based operating system with a front end from Google. Most Chromebook applications run on Google's cloud servers and display on the Chromebook. Tools that run locally are limited, but if the web is all you do, and you can always be connected, then a Chromebook is fine.
Thinkpad is a brand IBM created for selling laptops to the corporate market. When IBM left the personal computer market, they sold the Thinkpad brand to Lenovo. IBM manufactured some very good laptops, I've had three Thinkpads before my company switched to buying Dell. I have not bought a PC from Lenovo (which also took over IBM's desktop and workstation brands).
I'm not sure brand is important. Besides the three Thinkpads and two Dell Latitudes my company bought for me, my family has been through four Dell laptops and a Sony Viao. I've gotten the most useful service from the Dells, typically 3-5 years of continuous use. That isn't just about hardware, because Windows upgrades and changes of use have outgrown the capability of machines that were still running.
There isn't "just a laptop" because these have to be built for different markets to different price points. We've covered the Chromebook, a web-access device. There have also been crippled Windows PCs targeted to that market (but no longer) and low cost Linux PCs (which are really as standalone capable as Windows, just don't run Windows programs, so you have to get used to the freeware available).
First level, $400-$800 today, is the basic consumer Windows 10 laptop. These will be low-cost screens, slowest processors, modest memory and storage, although all of these capabilities increase with price. At Dell, this is the Inspiron series. For home entertainment potential, most of these still have an optical drive, for playing BluRay and DVD video, and writing CD-ROM and DVD-ROM. These will be built on metal or carbon-reinforced chassis, with plastic (sometimes reinforced) cases, sometimes metal (or looks like metal) trim.
Next category, starting about $800 and up to about $2000, and slim, lightweight "ultra" laptops. These have no optical drive. Some have no rotary drive at all, using only solid-state storage. They have better screen quality, although in smaller sizes, and at the top level, have performance matching high-performance desktop machines, but not multi-processor workstations. Typically the computer is built into a machined light-metal case. Examples: Dell XPS series, MacBook Pro. Some manufacturers label them Ultrabook.
Then there is an ultralightweight laptop/tablet 2-in-1, premium price and limited performance (e.g. Microsoft Surface series). Portability is more important than performance or capacity. The newest MacBook is an example of an ultralight that is not 2-in-1, you can't get rid of the keyboard to use it as a tablet.
There are gaming laptops, $1000-$3000, with fastest mobile processors available, lots of memory and storage (two disk drives is common) and discrete high performance 3-D graphics processors (which might have 10X to 100X the processing power of the main CPU, just to do 3D rendering). The least of these share processors with the top-level "ultrabooks" but are in packages more like the consumer laptop. At the upper end, they are like the original high-end Thinkpads, 7-8 pounds of laptop throwing off 200-400 watts of heat. ASUS is a leader in this market, although the top MacBook Pro is capable and Dell has just introduced an Inspiron 15 Gaming at the lower price points.
Then there business laptops (from Dell, Lenovo, HP) offered in the same price and size ranges, except that they are designed to be remotely managed, are not pre-loaded with entertainment software, and the gaming machines are replaced by engineering workstations, which might have multiple CPUs and the graphics processors are more often tasked as generalized mathematical processors, putting supercomputer power into a (heavy) briefcase. Workstation laptop prices can approach five figures, few people can make use of the capabilities.
