Have a Galaxy Ace ii X for ~2 years and recently it has been randomly shutting off. After the random shutoff I must wait a short while before turning it back on.

Once it is back on the %charge of the battery will report a new random number, but usually lower than before it randomly turned off. The phone is not overheating nor is the battery bulging. It still seems like a battery issue, but wanting to be sure before buying a new battery only to find out it is an issue with the phone. Do Koodo stores/stalls have battery testers to be able to check them? Or another store like Futureshop?

Have you downloaded any new apps recently? If so try un-installing that app.
There's apps in the playstore that can check your battery if you think that's the issue, I don't know if they work as I've personally never tried them.

I can't believe you've have had an Ace series phone for 2 years and never had an issue with it, the Ace series has always been known to have many issues even for an entry level device. Smartphones have come along way in the last two years especially the low end offerings which are now as good as the top tier devices from 2 or 3 years ago. I'd think about getting a new phone like the Motorola Moto G or Moto E as they're both great phones that have more up to date software and more powerful processors as well as better battery life than phones of their level from a few years ago.

Until you choose to buy a new device try a factory reset of the phone especially if you haven't done it in years. Just remember to back up your data like contacts, pictures, ect before attempting the factory reset.

Thanks for the advice. Gmail updated but that is about it apps wise (phone is pretty bare bones as I use more so for work).

Is the Galaxy S3 or Galaxy Core LTE worth considering, or the two Motos still seem better?

Go for the core if you're familiar with how Samsung phones look and operate (plus it has more storage and memory card expansion). The Moto G has a better display and simplified Android experience.
