DMG: I hear what you're saying and here are my honest thoughts.
I'm sure you will love the 16" MacBook Pro. It has the improved Magic Keyboard with 1 mm travel. It has the largest screen offered in a MacBook since your last upgrade. It will be blazing fast for office work and get excellent battery life, probably the best you've ever seen in a machine of this size. It's light, thin, it will work for years, and is overall an incredible machine compared to almost anything else on the market.
To me, the biggest questions are:
1. Can you live with the Touch Bar? Because it's definitely still there until this new redesign happens. I've been "stuck on" a Touch Bar Mac myself or the last couple of years, and while I hate it, I can't say it hurts my productivity too much. I love the Touch ID for logging into websites and unlocking the machine (which can also be done with your Apple Watch). The good news is on the 16" they at least returned a real Escape key so you don't have to look down all the time when you need it.
2. Are you going to be kicking yourself when Apple inevitably releases something amazing with the rumored return of real ports and no touch bar in something like 2-16 weeks? I personally hate the dongle life of 4-USB-C only ports, and the rumors suggest the return of a USB port, SD card reader, HDMI port and MagSafe, all excellent for families and business users. The rumored M1X processor will probably be measurably faster in specs, but I never met anyone who felt like an i7 or i9 Intel processor with 6+ cores was slow. Which brings me to...
3. Are you running any arcane, older or specific apps that might require Windows or run better on an Intel infrastructure than the Apple M1 line? I run a real estate office, and watching some of my coworkers battling Excel, Google Earth Pro and ArcGIS crashes since shifting some of them to M1 Mac Mini's has been tough. Big Sur doesn't seem as stable to me as previous releases, which is probably why Apple is releasing Monterrey so quickly. Ultimately I have to think any serious business user values up-time and stability over raw power. Also, you can't install Windows through Boot Camp (yet) on a Mac processor based computer (as far as I know,) which means your only option would be a virtual machine through Parallels or something similar. Windows also has good Apple firmware available to install drivers so the Touch Bar works in Windows as well, btw.
If it were me, I would wait the 1-4 months and see what Apple releases. My gut tells me you'll still have a great corporate discount available on this or another machine then, so price isn't necessarily the #1 issue. The Dell XPS/Precision or Latitude would also be great for you, or the Microsoft Surface 4 or Surface Book 3 (or 4 if they release it this fall). Though I'm sure you will love the 16" if you end up getting it, I just feel like... if I waited 7 years to upgrade, I wouldn't jump the gun 3 months before the biggest redesign of the MacBook Pro chassis in 5-10 years by Apple.
