Late to the party and looking for clarity here... I have a Legacy 2.5i. 

Should I still be aimed to get a Group Size 25 battery or am I best to get a Size 34?  I ran into a Service Bulletin that has me wary because it says the newly recommended battery is "bigger in size" but doesn't specify more than that.
Just trying to make sens of this so I can move forward with replacing the battery.

Get the Size 34. you can get the newer heatshield, or macguyver/duct-tape the older one to fit the 34.  nearly double the CCA.

I replaced the OE battery in my 2017 Legacy 2.5i Limited Jan 2022 with a Costco Interstate Group 25. Today I replaced the year old battery under Costco's 3 year warranty. I had to have the old battery jumped twice in 2.5 weeks after the car sat undriven for 2-3 days. (Warranty scam alert: they refunded my money for the old battery, then charged me for the replacement which is $10 more. FYI, a class-action lawsuit has been filed against Costco over their battery warranty.)

I think you should take your receipts to the Tire/Battery center and get your $10 back since you did return the old battery. I just bought my first battery from Costco, and got $10 back after returning the old one.
