I'm less sure about the state of open drivers with WL18xx. I'd suggest exploring that a bit more to see if it ends up dominating. For early WLAN, sometimes firmware and fragile DMA integrations were hard to work around. The wl17xx wl18xx driver is behaving OK with various SoCs with the mainline kernel at least as tested with SDIO. For the Linux kernel, often the most recent long term kernel is used, that is linux-5.10.y currently and might be linux-5.15.y at the end of the year. If you just need basic SoC support and wl18xx, then I don't see issues using current stable kernels. The SoC is fairly similar for peripherals for various omap3 devices that are still being actively used :) If you need to use out of tree hardware accelerators and and power management, then things might get a bit trickier.
