You're definitely onto something with the airflow issue—cellulose can be great insulation, but I've seen it get nasty fast if the attic isn't breathing right. Have you checked if your soffit vents are clear and properly balanced with ridge vents? Sometimes even small tweaks there can make a big difference. Fiberglass is itchy, yeah, but at least you don't have to worry about moisture buildup as much... Pros and cons either way, I guess.
You're spot on about airflow being key—seen plenty of attics turn into mold farms just from minor venting issues. Fiberglass might itch, but at least it breathes better. Still, cellulose done right can outperform it. Tough call, but sounds like you're thinking it through carefully...
"Fiberglass might itch, but at least it breathes better. Still, cellulose done right can outperform it."
Totally agree with this. I've seen cellulose insulation work wonders when installed properly—had a client who switched from fiberglass to cellulose and noticed a big improvement in comfort and energy bills. You're definitely on the right track by focusing on airflow first, though... that's half the battle won already. Good luck tackling the itchy pink monster up there, sounds like you're making smart moves!
I've dealt with both fiberglass and cellulose in several projects, and honestly, each has its quirks. Fiberglass is definitely itchy stuff—spent a weekend helping my brother-in-law redo his attic insulation, and even with full protective gear, I was scratching for days afterward. Not fun.
That said, I wouldn't completely dismiss fiberglass yet. Cellulose can be great when installed right (as mentioned above), but I've also seen it settle unevenly over time if the installer cuts corners or doesn't blow it in properly. Had one property where we had to go back after a few years because the cellulose had compacted significantly, leaving cold spots and drafts.

Couldn't agree more here. Proper ventilation and sealing air leaks will make a bigger difference than just swapping insulation types alone. Whichever route you choose, just make sure it's done carefully—insulation isn't something you want to revisit every couple of years. Good luck with it...
I had a similar itchy nightmare when I helped my parents redo their attic insulation last summer. Even with gloves, masks, and long sleeves, that fiberglass stuff finds its way in somehow...ugh. But honestly, after sealing up some drafts around the vents and properly installing baffles for airflow, the difference was night and day. Insulation type matters, sure, but good airflow management is key—otherwise you're just throwing money away every winter.
