I opted for the diehard version over OEM:
https://shop.advanceautoparts.com/p...-ca-60-min-reserve-capacity-h3-xev/50001096-p

It's a drop in replacement (size wise) and doesn't require any modifications.
I brought my old OEM H3 LVB into Advanced this morning, they ran the "electronic" load & capacity test, it was still showing a good condition showing a capacity of 426 cca which was more the the rated 390 cca, I could have rolled the dice and rolled with it for a longer period, erring on the side of caution swapped it for the Diehard equivalent that's rated at 525 cca.

I'll revisit the LVB battery in 4 years to see how the replacement is performing, now that we have the new BMS and improved LVB management strategies from prior OTA's

I refuse to buy any products marked as vehicle type specific. It's an h3 group agm battery.

I can get the ford one for about $250 CAD if I needed it.

Nearly $300 USD for that die-hard one, ouch.
AutoZone sells a replacement.
