That said fish is quite configurable¹, it just have pleasant (well maybe not to you) default that you can change.

I think these projects are extremely opinionated and they will inevitably drive a lot of users away. Both fish and GNOME strive to provide "good" defaults out of the box but those defaults will never appeal to everyone. I ended up liking fish but I still despise GNOME and everything related to it.
I ended up back on zsh. It's a real shame, because fish adds quite a lot in terms of improved subshell syntax and intelligent string manipulation.
Seems like someone should have been able to disable the suggestions using a plugin or something, given that IIRC fish has a plugin interface. But as far as I can tell no such thing exists.
