You have the full power of Emacs to your disposal.

I have never used WezTerm but from a quick look, it seems you can quickly copy text ace-jump style.

In Emacs you could use e.g. avy to do the same, but there is probably a bunch of other similar packages that do the same.

And additionally you're not restricted to just select/copy a word. You can freely move around and use e.g. expand-region or similar to quickly select more.

It's Emacs after all, the possibilities are endless ;)
