Is Fiber to the home's GPON different in how it connects to the web via DNS than DOCSIS cable?

I found something strange when I had Fiber To The Home (FTTH) installed recently. Some web pages were very slow to load even though I have 940/980Mbps speeds. Digging around in Google, I found two things that sometimes radically speed things up. One was to set my DNS server addresses to Google's fixed addresses for ONLY IP4 (IP6 does NOT seem to be supported by my ISP). Next, I found that clearing my DNS cache ipconfig /flushdns helped images to load quicker. The pages that load slowly at first, usually load almost instantly once they have been cached.
Is there a fundamental difference in how my ISP EPON/GPON headend treats a fiber connection vs the old DOCSIS headend? Is there a difference in how they cache an IP address? Would a cold load of Windows 11 DEV help? Doing some massive Google research now. This is heady stuff!
