I'm thinking of picking up an OBD II scanner to check for codes. My car has some driving issues and maybe I can check for codes and work out a plan. I could take it to a mechanic but I don't have one I can trust yet.

So any recommendations for reasonably priced scanner that supports a 2018 Impreza?

Thanks

As mentioned elsewhere, if the only thing you want to do is read codes, a $10 BT dongle and a phone app is going to be just fine.

But if you want to do more involved diagnosis, you'll need something better. HF has Icon branded diag tools, like this one (which is the cheapest of the three). I haven't used it myself, but Eric O from SMA has some Icon model that I've seen him use and be happy with.
