Help with sweaters! (I know it's late)

Long time lurker! So, over the past year I've been lurking, and over the past six months, I've been focusing on basics and getting correct fits in jeans/chinos and t-shirts. I've learned fit is king! Not that I was terrible with fit before. So, I'm ready to move onto some sweaters and gear up for fall and winter with season-ending sales and clearances.

Background, I'm a teacher and usually wear chinos and boots with a polo or button down to work (pretty standard MFA outfits). For weekends and after work, I'm working on fading some raw sanforized LVC 501, LVC 511, gap slim, and gap skinny.

So, I'm looking at incorporating some casual, relaxed aesthetic sweaters and texture- mostly some cardigans, and shawl collar cardigans. Here are some examples of the style I'm looking for:

I was wondering if I could get feedback on some of these sweaters or where to get similar pieces as I'm on a low end budget:

Target 1 (light gray)

sudaderas

Thanks in advance!
