Don't know about the last one you've mentioned, I am new to bass too (not to guitars) so I will tell you from what I've found out as a beginner,
I've tried the Ibanez and the Yamaha in the store and I can tell you that the Ibanez felt much better, it is very light (so is the yamaha) and very very comfortable, the body AND the neck. the woods give an excellent feel.
not sure about the others but the Ibanez has active pickups and a pot for "bass-boost" you can get a few types of sounds out of this guitar just by dialing different values on the pots and the boost.
they all have jazz pickup as the bridge pickup and precision pickup as the neck pickup, the SX ursa 3RN CAR (which I know nothing about) looks more like a fender precision bass and as such I guess it has the "slowest" neck as it's probably a little larger from the others at the end of it. you might learn something from my thread here
I got a Fender Squier Jazz Bass which I didn't like, eventually I've returned it and now I am going to get the Ibanez with flatwounds strings and actually excited towards it, it's an awesome bass, I've played it.
it also depends on the styles you want to play but if you go with this type of guitar you might also be able to consider Squier precision bass.
