I spent a long time looking at carriers lol The one we got is still a soft sided one like our old one but has structure with an internal cage that is steel. It's not an inexpensive one in terms of carriers you can get but there were a lot of features I was looking for. I have purposefully stayed away from plastic carriers because I wanted the easy access that soft-sided ones can give so I can reach him and try and comfort him and the one we got has many different ways to get to the cat.
This is the one we got (we got it in blue but you can also buy it in gray for a few dollars less)

He doesn't weigh anywhere near the weight limit but we got it for the size part so he could comfortably stand up all the way or lay out. It's hard to find large carriers! There are a good amount of photos you can see where people have big cats.
In comparison to our old one the bedding could be thicker although you could supplement with a towel if you didn't feel it was thick enough. We always have a few of his toys in there. I don't think he plays with them necessarily the times he's in there but just to give him the scent of
his stuff inside. The other downside is the shoulder strap doesn't have a padding like our old carrier but we use the handle straps more frequently. Anywho just thought to pass on one we found after searching for a long time
