I'm almost finished building my first enclosure! The mMar-Kel70. I'm looking forward to hearing how it sounds!
I'm having trouble locating felt/batting to use for lining here in San Francisco, so I'm looking at stuffing with polyfill out of a cheap pillow. How much polyfill do I put in there? From what I've read it seems you want to go about 50% full? The way I understand this is to get enough polyfill in there so that there's not much space left, but not pack it in at all.

I hadn't looked at auto shops, but the furniture/carpeting/fabric shops I have looked at either
- don't have anything suitable,
- want to sell me 100 sq ft, or
- are inconvenient to get to (I'm new here, so I'm without vehicle).
I'll have a look at auto shops though, thanks. Am I likely to get a better result out of felt lining?

Well, the point may be moot as you've "almost" finished the first box. It's easy to attach the felt "before" glue-up, but not so easy after, unless you have "toddler sized" hands.

I line all inside walls except for areas immediately proximate to vent openings
1/2" - 3/4" thick material if cut carefully to size will almost friction fit -it doesn't need to tightly "couple" to panels, just not fall out of place -
I use white PVA wood glue (Weldbond, etc)
I think only the 3" batting for wall / ceiling insulation - "rather fussy work" to pare down to thinner dimensions
This os 3/8", 9mm thick. You may need to peel off the "tin foil". I suspect it is the same felt we use but thinner. Someone in the US should check this out in person and report back.

This is 2" thick insulation density stuff... much less dense than the felt. Excellent for volume fill. Not really useful iining the walls of small boxes. Big boxes it would serve like, but be better, than fiberdlass (wall insulation density)
