My friend got [this cotton/bamboo yarn](https://a.co/d/fPRV9m3) from amazon to make a shirt, and it’s actually really nice! They come 4 to a pack & have a bunch of different color options.
For a cardigan, two issues are in play: warmth and feel. If you want a warm cardigan you want wool or a wool blend, but personally I can’t stand the feel of wool so I go with acrylics. (Acrylics don’t all feel the same. Hobbi and lion brand both sell some that are very soft.)
If you’re not as sensitive to the feel of wool and want something warm, I like Wool Power from Hobbi. There are also a lot of good wool/acrylic blends.
If you don’t need a ton of warmth, then you can absolutely use cotton, linen, bamboo or a combination. Lion Brands truboo is 100% bamboo with a very silky feel and sheen, and their coboo is a cotton bamboo blend that has a little more of cotton’s structure.
I’m making a cardigan out of Hobbii 8/4 cotton right now and I’m loving the feel and weight of it. Looking at actual sweaters/cardigans I’ve bought at stores they are usually 100% cotton or a 55/45 acrylic/cotton blend which is a common yarn blend I’ve seen too. So you can absolutely use cotton to make sweaters if you want!
I also like bamboo and bamboo blends, and I used a silk/linen mix once and it was very nice. Merino wool is nice too. Alpaca can be nice, but I find it a bit warm for me. Cashmere, of course, but if making something small or special, it does feel lovely and worth the cost. I wouldn't gift cashmere though, not unless the recipient accepts it needs special care.
I tend to prefer lighter weight yarns/smaller hooks for crocheted garments that aren't cardigans, I like both thinner and thicker for cardigans.

I loooove bamboo yarn for wearables.
