Having been through several migrations of various ERP's and finance packages with my company, we always negotiated a fixed price contract, then we go by the "Configure, don't customize" motto and we will change our processes to match the software whenever possible rather than trying to customize the software.
When we migrated to Oracle, this led to an on-time and on-budget deployment of e-Business suite (Then version 11.something). There were a couple of areas where we needed custom code, mostly due to some external interfaces we needed, but most everything else was just configured out-of-the-box.

For the vim example, don't forget to install the Gemini plugin...

-- lazy.nvim
{
'kiddos/gemini.nvim',
opts = {}
}

Did you try the other versions?
vim blueberry
emacs peachpit

They need to make search results more helpful. It's all just generated lists and ads at this point.

I have a 10G Ethernet card on my iMac via an external Thunderbolt PCIe expansion chassis. So, OS X can use 10G.
I have a third party software iSCSI Initiator installed, so OS X can use iSCSI.
You fail to mention NFS, which OS X supports natively.

Aside from CPU upgradability, the 6 Thunderbolt ports means that this particular Mac Pro is the single most expandable Mac on the planet.
You can add a TON of PCIe expansion boxes to give you a ton of slots as needed, including additional graphics cards, RAID cards, etc.
Since everything is external, you also don't need to worry about upgrading the internal PS of the Pro or worry about cooling needs of the computer itself.
Yes, it'll mean that everything is external, but it also means that everything is "pay as you grow" and keeps the computer itself nice and small and hopefully less expensive (we shall see).

No, it's not for everyone, but it is an interesting design and it is expandable.

I would consider getting a large sand blasting cabinet.
