desktop [install- or configur-]ation issues on Dell workstations?

[Frank Fenderbender]

In terms of platforming FreeBSD, I've decided to stay away from systems of old, which tend towards issues of compatibility, availability, and faded support.
So, I am trying to fit a computer system to FreeBSD rather than the usual "other way around". 
I have a Dell account to work with so I am looking for a Dell workstation as my FreeBSD platform.
There are many ways to configure the hardware and its add-ons so I want to try to get the "best fit" for FreeBSD desktop, running as both a development. and compatibility-testing platform.

I have seen numerous issues with NVIDIA's graphics, both on Ubuntu and BSD discussion websites; Dell's selection set is {NVIDIA, AMD}.
I'm certain that other issues, of which I hope to learn about beforehand, can be avoided more or less, from how the FreeBSD installation and configuration find the platform onto which it will reside.

I am asking for considerations and suggestions that you have encountered, maybe even with Dell platforms themselves -- for good or for bad -- so that I can best address them in selecting Dell options ahead-of-time. 

I will be developing and testing applications based in python3, pyqt5, CoreData, and sqlite3.
I'd appreciate and value your input.

I tentatively have the following system in my Dell "shopping cart" and want to quell my leeriness with others who have been near similar  installation, configuration, and usage criteria, so that I may modify my cart's choice(s) before pushing a "buy" button.

If anything pops out from the list below as problematic, or if a key component is missing, I would appreciate your "heads-up".
I presumed that it will be easier to clear-and-install on a system with pre-installed Ubuntu  than one with Windows 10, noting that it is definitely cheaper....

 Thanks much for your review,
"frank"
