Can't fish Ethernet? Use "invisible" fiber instead

I had a lot of trouble with this when having my contractors run cat6 in my house during a recent renovation. Their electrician kept saying "it's done!" and then I'd test it and find that I was getting only 100mbps. Then they'd re-terminate the ends and a few more of the runs would get full speed when I re-tested. Repeated this cycle a few times until they all worked.

I had my electrician pull the CAT6A in my current place, but then I terminated it all myself.

That would 100% been the right move. Some friends of mine with networking and ops backgrounds told me, "never trust an electrician to do low-voltage work right." After my experience with this one, I think I should have listened!

Absolutely. I've seen two examples of electricians using wire nuts to splice two runs if UTP wire together. There's also a general disregard for keeping the pairs twisted as close to the termination as possible.
