I recently installed Microsoft Office 2019 on my MBP M1 but I really don’t know if it’s the Office 32 or 64bit version.

Is there a way to tell on MacOS which Office version I am running? 32 or 64bit?
 
32-bit only apps don’t run, but apps that have multiple architectures, including 32bit, run on current macOS versions.
Example R-Name on Apple Silicon Sonoma 14.2.1 https://www.jacek-dom.net/software/R-Name/

mdls /Applications/R-Name.app | grep -A 3 kMDItemExecutableArchitectures
kMDItemExecutableArchitectures = (
"x86_64",
i386,
ppc

file /Applications/R-Name.app/Contents/MacOS/R-Name
/Applications/R-Name.app/Contents/MacOS/R-Name: Mach-O universal binary with 3 architectures: [x86_64:Mach-O 64-bit executable x86_64] [i386:
- Mach-O executable i386] [ppc_7400:
- Mach-O executable ppc_7400]
/Applications/R-Name.app/Contents/MacOS/R-Name (for architecture x86_64): Mach-O 64-bit executable x86_64
/Applications/R-Name.app/Contents/MacOS/R-Name (for architecture i386): Mach-O executable i386
/Applications/R-Name.app/Contents/MacOS/R-Name (for architecture ppc7400): Mach-O executable ppc_7400
 
Archichect is a simle GUI app which tells all sorts stuff about an app.

I found something under System Report/Software/Applications and I selected an Office application and next to Kind (from the below pane) it says 64 bit.

Would this also be the correct location to check as well?

Go to the Applications folder, and then go to the Utilities Folder, and then open up System Information.

On the left pane of System Information, scroll down to Software, and then click on Applications. It'll generate a list of all the software installed on your computer.

For the Mx series, software is either:

Apple Silicon. This is native software written for the Apple Silicon processor.
Intel. This is software written for 64 bit Intel processors, and being emulated through Rosetta 2.
Universal. This is software that has binaries for both 64 bit Intel processors and Apple Silicon.
iOS. This is software designed for iPhones/ iPads that can run on Mx series processors.

32 bit Intel software will not run on Apple Silicon. 32 bit Intel applications (and 64 Power PC applications, and 680x0 applications) will have the application icon gray out with a "no" 🚫 symbol across the application icon.

Yes, it's the same as the MacRumors guide describes, only the column name may vary.

This is how a 32-bit only app appears in Ventura - System Information - Software - Applications
32-bit (Unsupported)

and in Finder

The app - uTorrent Classic https://www.utorrent.com/downloads/mac/
 
I just double checked under System Report/Software/Applications - Microsoft Word, Excel, and PowerPoint.
And next to the "Kind" it is indicated as "Universal".
 
And Apple's current documentation:
Apple Developer Documentation - Building a Universal macOS Binary
https://developer.apple.com/documentation/apple-silicon/building-a-universal-macos-binary
"An app that supports only the x86_64 architecture must run under Rosetta translation on Apple silicon. A universal binary runs natively on both Apple silicon and Intel-based Mac computers, because it contains executable code for both architectures."
