Affordable PCIe 5.0, With A Catch
ASRock’s Phantom Gaming Z790 RIPTIDE WIFI has both a PCIe 5.0 16x slot and a PCIe 5.0 x4 M.2 slot, however if you want to use them both then that PCIe slot drops eight lanes and becomes an x8 slot. The effect that will have depends on the GPU you are using, as eight lanes of PCIe 5.0 will be enough for many of them. You could also stick with the three M.2 Gen4 slots if you are concerned about your lanes.
If you are looking for a board with everything mentioned above, plus 2.5 GbE LAN, WiFi 7 and multiple Gen 3 USB of both Type-A and C then check out The FPS Review’s look at this Riptide board.
