What is good practice? - #10 and smaller wires solid or stranded?
I always liked stranded for #10 and solid for #12 and #14. But that was just my personal preference. (#10 solid is tough to work with)

Stranded is easier to pull.
IMO for raceway installations #10 solid should be banned.

When I am inspecting and see solid, I have them pull it out and install stranded.

I believe this helps to build character in the guys.
This is good enough reason for me.
Pull stranded, use fork terminals.
Not all devices are UL listed to have fork terminals used on them.
(Just had that issue come up in the field.)
