Barracuda is Seagate's basic value line so makes sense everything is SMR. Especially since you're shopping for 2.5" laptop drives.
The ironwolf drives are more enterprise focused so they're noisier, might be why it's cheaper. But they're a good option all around. (Frankly day to day hard drive prices are random anyway...)
No they don't typically come with any hardware to hook up, it's assumed you plug it into your computer. However you can get USB to SATA adapters, with an external 12v power brick for mechanical drives, fairly cheap on amazon et al. I have one from U-Green that works fine and is also a USB hub and SD card reader. They're great to have around just in case.
I have a U-Green SSD reader that I needed to test an SSD in the past. The drive was a bust but the tool was neat! I’ll go looking for the HDD version too. Does… it supply power too?
Those adapters supply 5v power from the USB port, but SATA adapters capable of running hard drives usually have an external 12v power brick, as most full size hard drives need 12v for the drive motor.
Now, that said, I think a lot of 2.5inch hard drives do use 5 volt only and might boot up fine from an SSD SATA adapter. It's worth trying your existing adapter as is and seeing if it starts and recognizes the drive.
