I ran into a very similar issue when I moved from an Asus router on Advanced Tomato firmware to a PC running OPNsense. I repurposed the Asus to be a wireless access point. All the hardwired devices in my house worked fine. But every wireless device going through the Asus would get random and frequent DNS related timeouts or rejections after a period of time.
After much fiddling and trial and error of setting son the old Asus Advanced Tomato settings, I discovered that turning off Cut-Through Forwarding (CTF) fixed the issue. No clue why this setting would make a difference with DNS traffic. But since I turned it off and rebooted the Asus, I have been problem free for days.
