I use middle click paste all the time, but the title is misleading and clickbaity. At least on GNOME’s side they’re discussing about disabling it by default, not completely. While this is annoying as long as the setting isn’t going away I’m fine with that and I understand the reasoning behind it.

Pretty much the same as any other incarnation of openwrt, just without a lot of the compatibility headaches and weird installation processes that you typically have with other architectures. It’s just install and forget pretty much.
As for the link speed, you can just
cat /sys/class/net/eth*/speedas with any other linux system. Not sure how your configurations stopped working or broke, maybe your storage got corrupted or something? Hard to tell, but I doubt openwrt caused it on its own, it sounds new to me.
