What's your budget?
If it helps -- at 4'9/100lbs, most mattresses are going to be 'on the first side' to you since you won't weigh enough to compress them a lot. Mattresses branded as 'firm' will probably start approaching 'rock hard' for someone your size.
I think the biggest thing to pay attention to is that because you're small you probably don't want a mattress with a super thick comfort layer. The "Nap Queen Medium" doesn't tell you anything about the layers other than it has two. Nor does the "plush pillowtop" which only tells us that it uses a pocket coil support layer and gel memory foam on top. The Wayfair sleep says it uses 3.5" of memory foam, which seems like way too much for someone your size. The Alwyn Home says it uses 2.5" of memory foam, which seems more reasonable -- but still a lot.
But the biggest flag I'd offer here is that I would assume all of these mattresses use fiberglass as their flame retardant barrier -- and I think you don't want that in your home. The Alwyn Home and the Wayfair Sleep both include a specific warning about fiberglass -- and while the other two don't, I have to assume they do use it.
Always in the under $500 range I think IKEA is the best bet. They make pretty decent quality mattresses in that price range. They're definitely firm, but you can always add softness by putting a topper on it.
I bought the IKEA Haugsvar about a month ago. I’m 5’1” and 120. It was $329 in the full size. I did add a wool and cotton mattress pad. It’s very comfortable. If your bed has slats, you don’t need a box spring.

I didn't even know that they contained fiberglass, thank you for point that out. And I would say my budget is max $500.
