I don't think the Mac Mini's ports are a problem - thanks to the retention of a couple of USB-A, HDMI and Ethernet ports. That discussion is for the MacBook/Air/Pro range.
Where it comes in to the Mini argument is when "4 TB3 Ports!!!" gets cited as end-of-argument when comparing the Mini to other systems in the PC world where, indeed, you'll rarely find more than 1 or 2 Thunderbolt ports (if any) but they may make up for that in other ways. Case in point would be the Intel Hades Canyon NUC which only has 2 TB3 ports but has oodles of other ports to make up for it and a semi-discrete GPU and a pair of M.2 slots for internal SSD expansion - so many people won't need to connect displays, high-speed external SSDs, eGPUs, extra Ethernet, etc. or legacy USB2/3 stuff via the TB3 ports. I'm sure that having more that 2 TB3 devices connected to a Mini will be rare c.f. having one port driving a second display and another one or two with USB3.1g1 or lower devices.
My counterpoint to the Hades Canyon would be that the only reason Intel was able to cram that many ports in that size box is because they moved the PSU external, which is nearly as big as the NUC itself...and jeez, having carried around a Thunderbolt Dock or two with a laptop in my day, they are a pain in the @$$ to have and please make sure you don't forget it or you are in trouble.
With the mini, as long as that Figure 8 is not proprietary, you could buy a second one for an alternate location and place the mini in a Messenger bag if you prefer not to roll with a MBP or an iPad just won't cut it.
I like the Hades Canyon, but they do not come cheap, especially since Intel really doesn't sell computers, like Dell or HP and NUC tend to turn up for sale with all kinds of stuff preconfigured.
On SimplyNUC, the 8809 G (GH GPU) is $948, barebones and the GL is $719.98 barebones -
https://simplynuc.com/hades-canyon/ - Adding 32GB is $300 and a decent 970 Pro NVMe 512GB is another $200, so I am at $1220 or $1448 without Windows 10.
The equivalent Mac mini 3.2GHz i7, 32GB/512GB is $2099, so I get it...I can drop $300 back to $1799 with third party RAM. I don't mind the premium on the price, I know I don't get Vega. For now, I would not need it and I would rather wait for Vega Instinct 7nm consumer GPUs next year. I get a 6c/12t CPU now, so that is a point or the mini over the Hades Canyon. I could choose the i5 on the mini, save another $200 and still out run the Hades Canyon on CPU, if not GPU.
All those ports are nice, though, but I suspect the PCH could be a bit overloaded. I also heard the GH version ran pretty hot as well, but I have not seen proof, just conjecture.
The mini is still where I would want to be...my most recent experience with Windows 10 was clearing out a particularly nasty trojan that could survive reboots, manually editing the registry to remove the startup routines, evaded MS Defender and had me turning on Services manually to fix the infamous Airplane Mode issue that once fixed, still prevented Wi-Fi from working. It took me an entire Saturday that was better spent doing something else. FYI - It was not my computer, but a relatives.
So, yeah, I will pay the extra for the mini and macOS.
