Even if air were gelatinous enough for convection to be meaningfully affected by making baffles that way, you're mostly just making the air gap smaller, allowing more thermal bridging.

Canada doesn't use the IRC.
Also, fireblocking materials in that reference include glass fiber batts... so OP's literally proposing to fill the wall with approved fireblocking by that reference.

9.10.16.2 is the relevant article, and they are filling the wall with insulation, so fireblocking is not required between the wall and floor inside a dwelling unit.

The issue they are pointing out is that the air gap in the wall is connected to the concealed space in the floor assembly. If you fill the studs with insulation, you are excepted from the fireblocking requirement.
Otherwise, you can block the space between the framing with lumber or plywood or drywall.
