Motherboard Specifications on MotherboardDB

This is a good resource, but I with it was easier to search for motherboard with 2x PCI-E @ 16x

May I suggest adding some information that enthusiasts are interested in? For instance, VRM, debug LEDs, RGB headers, pci-e conflict information (eg. if you use pcie_0 alone, it runs at x16, but if you have pcie_1 populated they both run at x8).

That's a really well done spreadsheet. It's not my project, but I believe the creator invites contact via email.

It's a shame I see so many good spreadsheets like yours, almost always on Google Sheets. A social network based on spreadsheets would help surface this content, and if clear licensing were included, instant remixable data would have me beating down that site's door.

I found this during research and thought I'd share. It could be better, but it's a one-person project labor of love, so I'm pretty forgiving.

For new-ish parts, PCPartPicker.com is still the single best resource for this info, but their info isn't always entirely accurate. For a given board I was researching with USB3.0, PCPartPicker listed it as having USB3.1Gen1 support. For compatibility its built-in checking is pretty good for what it does, but if your use case demands specific I/O ports/functionality, especially dicey things like Thunderbolt over USB-C, always discover the ground reality for yourself from first-party sources, such as the OEM/vendor.

While the general idea that discovering sockets for different CPUs can be challenging, all AMD Ryzen consumer CPUs use the AM4 socket, including the Ryzen 4000 APUs. That hasn't been hard to remember, in my opinion. (But sure, Threadripper and EPYC are different - TR4 and SP3.)
