I also use wire wrap wire. The Kynar insulation is designed to not cut
thru against a sharp corner wire wrap post, no need to insulate
ferrite. I use 26 or 30 gauge. Multi colors are fun and available in
small spools on ebay in both gauges. No messing with Xacto scraping off
the polyimide insulation on magnet wire is another big plus. A small
multi-gauge wire stripper is a good investment to prevent nicks. Hakko,
Klein, and Ideal make them, check Amazon.

I wind matching transformers for receiving antennas with 30 AWG
wire wrap wire. A BN73-202 binocular core will accept up to 18 full
turns (36 passes). The insulation is very tough and it will not short to
the ferrite core. The insulation is so tough that you'll need a wire
stripper intended for 30 AWG wire wrap wire.
Here is an article about the dangers of ferrite cores damaging
the insulation of magnet wire. Like Grant, I've been using
Kynar ("wire wrap") wire for years on my binocular cores.
