Here are some minor details that I will be assuming when writing this answer:
There are no good laptops with HDD booting anymore, so I will assume an SSD is also ok. Windows is currently also only Windows 11 on new laptops but you can still install Windows 10 on most of them.
The one I would reccomend is the Framework 16 DIY. If you spec it out with 2x8GB RAM and a 1TB SSD, you would come out a little under $2000. For that kinda money you are getting an ultra repairable laptop (I have the Framework 13 and I have heared that the 16 is even better) with a Ryzen 7 7840HS and later the possibility for a GPU. You can connect up to 3 external displays if I'm correct (although you could technically have 6 HDMI ports but that's just stupid). The only downside is is that it has a backlit keyboard but I think you can turn it off. There is no option to buy a Windows 10 license (thanks Microsoft) but you can still install Windows 10 and then buy it later in the Microsoft store
