The thing with blankets in the crib is that you're not watching every second to make sure baby doesn't wriggle under the blanket. That's not a problem with a stroller, because you have baby in your sight all the time.
For car seats there are blankets with holes in the back and velcro fastenings. You put the blanket in the seat, thread the straps through the holes, put baby in, fasten the straps, and then fold the blanket over baby and fasten with velcro. It's a bit like a loose swaddle, and the blanket easily stays put, without risk of covering baby's face.
As for swaddling: some babies like it, some don't. Don't spend a fortune on special swaddling products until you know. In general you swaddle for sleep, although I've heard of restless babies who latch better on the breast when swaddled. You definitely don't swaddle all the time, baby needs to be able to move around when awake. And like I said, they don't all like it. My oldest needed it in the early days to be able to sleep, so we swaddled. My youngest hated it with a passion, so we didn't. He needed my presence to sleep, not a swaddling blanket.
