You can choose current-generation hardware from a company that chooses to implement less advanced wireless specifications. For example, the gl-inet Flint 2 (MT-6000) runs a fork of OpenWRT out of the box and can be flashed with stock OpenWRT snapshots. That's a very modern piece of hardware that will do wifi 6 (not wifi 6E/7).
So hardware-wise you get the current gen, software-spec-wise you get one generation behind. I don't think practically speaking you're going to feel much pain from using Wifi 6 for the next few years, as it can saturate a 1Gbps link pretty easily.
Pfsense (on a Proxmox VM, on a laptop with 2 NICs), tp-link managed switch with PoE on half the ports, all-in-one ASUS box configured as an AP only (and switch). It's only WiFi 5, but in a pinch that could go back to doing everything. Rock solid, with no reboots in years other than what ended up being unnecessary ones. Went 390+ days at one point on pfsense.
