The ideal materials are pretty much always going to be metal, wood, or acrylic plastic – these are good, hardy materials that will outlive anyone. However, I do find that wireframes are prone to denting and bending, especially with a lack of adequate support. I used to work with metal a lot, and the slightest bit of pressure in the moment will turn even the strongest looking wire into putty, so I’d be hesitant to go buying something made entirely from metal wire with a few plastic joints.

Much like the first option on this list, this one has only six storage shelves, although the layout of this one allows for a greater surface area by leaving the tops of three of the cubes exposed. It's acrylic, so maybe a tad sturdier than the wireframe, and marginally more expensive. This is more in the direction I'd err as it affords greater space and can blend nicely into a room's décor.

While the shelves on this unit are made from wires, the frame consists of metal rods that afford a lot more strength than a fully wireframe build. It's almost double the price of some of the previous options but it certainly ticks a few more boxes. There's a fully open design, allowing for access from either side, as well as from the front.

Everyone's standard go-to for any furnishing solution is IKEA. Their products don't afford much in the way of customisability, but they're reliable and affordable. The wooden frame is probably the sturdiest of all the options thus far, albeit somewhat more restrictive than the previous shelves as well.

Of all the options I've listed out so far, this is the only one that was explicitly designed with board games, and the mentality of an enthusiast like me, in mind. It's on the pricier side but there's a lot to like about it. The open design affords plenty of accessibility, the mixture of metal and acrylic materials assures a high degree of sturdiness.
