I'm building a PC for 3D modeling, software development and virtual machines. I have 64 GB of DDR5-6000 CL30, an RTX 5070 Ti, an NVMe SSD and a SATA SSD, and I'm planning on a Ryzen 9 9950X.
I know to check the socket and chipset, but what else should I look for in a board that will last? Gaming isn't a priority, and I'm considering keeping it mostly offline with Windows 10.
Start with the connections you actually need, then compare reasonably priced boards that have them. Count rear USB ports, check the network and audio connections, and make sure there are enough M.2 and SATA ports for your current drives plus anything you might add.
A pricier board won't automatically make the machine faster. For that CPU, though, look for independent testing of the board's power delivery and temperatures under sustained heavy workloads. That's more useful than buying a flagship just because it has a bigger feature list.
Read the storage and expansion sections of the manual before buying. Boards can share connections between M.2 slots, SATA ports and PCIe slots, so adding a drive later might disable a port or reduce the graphics slot's available lanes.
Also check the generation and lane width of each slot. A B850 label alone doesn't tell you whether a particular board has PCIe 5.0 for the graphics slot or how its M.2 slots are wired. Buy the layout you can use, not just the newest number on the box.
Don't overlook the BIOS and support side. Check the board's CPU support list and whether it needs a BIOS update for the 9950X. A BIOS update feature that works without an installed CPU can be handy if it ships with an older version.
I'd also check the memory support list for your exact kit, including its capacity and speed. A listing isn't a guarantee, and an unlisted kit isn't automatically incompatible, but it gives you another useful data point.

That helps. A BIOS interface I can live with matters to me too, so I'll look at screenshots and manuals before narrowing it down.
Check Windows 10 driver availability for the exact board before committing. Look for chipset, network and audio drivers, and check support for your other hardware too. If the machine will be mostly offline, download what you need ahead of time.
Also consider the security and software support implications of running an older operating system, especially if it will occasionally connect to a network.
Think about the physical build as well. Make sure the board fits the case, has the fan and front-panel headers you need, and leaves room around the graphics card for any expansion cards you might want. A smaller board can be perfectly fine, but its slot layout may limit future additions.

Check the rear USB layout specifically, not just the total port count. Some of that total may depend on case connections.
