When is a SPA quick? I still have yet to see this claim EVER be true.
I usually also set up a service worker to prefetch and cache the rest of the site while cache busting specific files on subsequent visits.
Personally I use SPAs for offline support and MPAs for "portals" and brochure/marketing websites or blogs.
That's really long.

You could build MPAs that offer offline support (and I have) but I find that you spend a lot of time writing the same render logic twice. Things might be different now with Next/Nuxt but when you're using PHP or C# it sucks to write the view render logic twice.
Like any technology, using it in the right place helps. This is great for documentation where the template and content slots are super consistent, for example.
There are places it’s not a great choice. It isn’t inherently worse, though.
This is pretty much the default and a given for everyone who visits your site... except you. As the author, you likely use your application more than most users, you use it on a work machine (which has a smaller, more niche browser history), and you use it with the sort of network connection that software developers demand: you know, excessive.
We see what we expect to see, what we want to see, and most of us don't challenge that, or only do it perfunctorily. And if someone else does? Well that's just crazy talk. See? Everything is fine.
Accessibility with said SPAs is still a pain though. Even when you use correct semantic elements instead of DIV soup, the DOM usable by screen readers changes “out-of-order” frequently in SPAs, requiring lots of extra work to ensure an accessible experience.
