Why would you not go for a solid copper filled via than a plated via?

Last week I send my PCB to the supplier for making trial samples and batch manufacturing. After their checking, they asked us whether choose solid copper filled via or a plated via. No idea to decide.

A solid, copper (not solder-filled) via is going to cost you a lot more money. Because it adds processes. Unless a via has too large a resistance.

Solder filling will improve resistance to some extent.

Why does flexible PCB need stiffeners?

When I browsed some comments online, I see someone recommends stiffeners to apply on flexible PCB. Very confused about that? Is it a formal design?
