Just a little update - I just flew my first solo. Was a bit exciting for a few reasons. There was a slight crosswind from the left on a left pattern, but it was also a sunny day and quite a few thermals/updrafts/etc around the airport. Also, temperatures are dropping which means aircraft performance is improved and then without the instructor in the right seat it is even more improved. The C172M I've been learning in really likes to glide, so it took two go-arounds to really get the hang of things (too high the first two times).
I was probably a bit nervous as well as it felt like the plane was really jumping for a few of those thermals (not really anything dangerous as my speed was near the top of the white on a go-around started from fairly high up).
On the third downwind I transitioned earlier and just told myself to relax and widened my pattern a little, and that set me up for a pretty good approach. I hit an updraft towards the end but coming out of it I still managed to get down in time, and while I could have probably held the plane up just a bit longer it was probably my smoothest landing to date (seemed like less control force was needed on the roundout - maybe due to lower weight?).
I feel like I'm well on my way now - still could use work on the landings but I feel very confident with navigation and instruments (that is probably due to having spent many years flying PC sims). I'll probably talk to the CFI about scheduling the knowledge test one of these days...
