I would think an inflatable boat would have too high of risk of getting a hole from a hook and then sinking. A float tube might work but I wouldn't think so if the tubes were anything less than hard plastic or aluminum
I use a friend's 10' pond bass boat. They're called something to do with ponds and they run a couple hundred dollars brand new. The basic ones have removable raised seats and mounts for motors at both ends of the boat. They have basically a catamaran hull and are limited to small motors and trolling motors which is usually plenty for most ponds. A jon boat of the same length seems to work just fine though, I've used one. I've used a paddleboat too but they're very restricting if you cast your line or fight fish much. A trolling motor does wonders for saving time and pain. Unfortunately I killed the only one we had when fishing line wrapped around the shaft and I tried to keep it running. A jon boat or a paddle boat doesn't have to have a trolling motor or good seats. But you need good seats and a trolling motor that's easy to reach in those pond bass boats or you can get some back pain real easy.
Which boat would work better depends more so on the budget you have for a pond boat. But IMHO anything made of plastic wouldn't last long unless you have zero branches/stumps/rocks in your pond and are careful with your hooks.
If it can have a trolling motor and it isn't too big or hard to pull in and out of the water it should work great. A trolling motor isn't required though but it is a great invention nonetheless.
