Precision 5xxx/7xxx does not have copper NIC (current version(s))
Precision is 15/17" formfactor.
Precision 3xxx is basically the 15/17" version of latitude 5xxx 14" series.
I highly recommend the 14" class of laptops over 15/17" for everything except coding.
I have even given up on that since you can daisy chain Display Port. I have a travel 19" monitor that fits in my backpack and weighs 1 pound. I have to admit I just carry tons of dongles for the same reason almost every case in our company has a pair of .50 reading glasses in them. I carry a 2020 13.3" Macbook Pro which I find myself using more and more of. I am waiting for someone to leave so I can grab one up that has the esc key as a hard key. I also carry an X1 Carbon Gen 4 I think, it is a beast with dedicated graphics and 32GB of RAM. I have Fedora Linux on that box and I run VirtualBox so I can boot Windows if I need be. For lighting and sound we have dedicated laptops of various vintages. Video I use Dell SFF computers. They fit in a Pelican and are thermally much more stable than a laptop. The streaming machine with OBX is a 19" Supermicro.
Lots of different tools for different jobs. I was a Thinkpad guy for 25 years. If I was buying a Windows Laptop Dell would be my choice too. The XPS's are very nice lightweight machines IMHO, I think as nice as the X1 Carbon and the keyboard is better.
I don't know about you Nathan but I still have a desktop too. Google Drive and docs, Having our AD in Azure and 1/2 the apps migrated to AWS EC2 I don't install much software anymore but I have two 32" 4k monitors and two ancient 21" 4:3 Samsung 214T's. These are medical imaging grade monitors. I find that the 4:3 format is better for shell windows and it is so easy on the eyes. They are getting hard to find. I have a stash of about a dozen and I relamped and replaced the inverter caps that go bad in all of them so they should cover me until I am dust. But anyway I still like to work with the desktop all day, I have a killer keyboard, graphics cards. 64g of memory and it doesn't make any noise. The laptops stay in the backpack.
